Around 60 women marched to Harley Street today calling for private clinics to replace PIP breast implants for free.
The group met in London with placards which read "Toxic Time Bombs" and "Health Before Wealth".
Their first target was The Harley Medical Group, which fitted the implants in almost 14,000 British women, and has said it will not replace them free of charge.
The firm fitted more of the implants than any other UK cosmetic surgery firm but claims replacing the banned implants would put it out of business.
The demonstration, which was organised on Facebook, then went to the office of Transform on nearby New Cavendish Street, which has also said it will not replace the implants free of charge.
Insurance consultant Mia Wood, 32, from Doncaster, South Yorkshire, said: "I'm angry, I'm frustrated, I'm crying every day.
"They are so happy to take our money but not prepared to help support us."
She said the women want the private clinics to replace their implants - not the NHS - because "we've paid for a service".
Ms Wood added that she cannot afford to pay the cost of almost £3,000 which she has been quoted to have her implants replaced.
Gemma Pepper, 29, from Darlington, County Durham, said she was distraught when she first found out there was a problem with the implants.
"I was in tears for about three days. I hadn't slept.
"I'm feeling a lot better now that I know we can fight back after meeting these amazing ladies," she said.
Stacey Williams, 25, from Portsmouth, complained that clinics which have gone into liquidation since fitting the implants and reopened under a different name are offering no support.
"They say because they are a different company we aren't covered any more."
Meanwhile the Government is running a national press advertising campaign this weekend advising women what to do if they have the implants.
Adverts are appearing in national newspapers and will be featured by websites from Monday, while GP surgeries and other parts of the NHS will be urged to display them.
The advice reiterates the Government's view that there is no evidence to support routine removal of the implants unless women have symptoms such as pain and tenderness.
It stresses that experts have found no link with cancer and there is no clear evidence of an increased risk of harm compared to other brands of breast implants.
Around 40,000 women in the UK received PIP implants manufactured by the now-closed French company Poly Implant Prostheses (PIP).
The implants were filled with non-medical grade silicone intended for use in mattresses.
The adverts tell women to find out if they have PIP implants by checking their medical notes free of charge.
Those women who had them on the NHS - around 5% of the total - will receive a letter in the next few weeks.
All women are urged to speak to their GP or surgeon, whether they had the operation on the NHS or privately.
The adverts say patients who had their surgery on the NHS will be able to have the implants removed and replaced free of charge.
Women who had the implants done privately will need to speak to their clinic to see if they will also replace them for free.
If a private clinic refuses to do so or no longer exists, the NHS will also pay to remove, but not replace, those implants if the woman's GP agrees and there is clinical need.
Clinical need may include a patient who is extremely anxious about the implants, or if there is a medical reason.
Health Secretary Andrew Lansley said: "My aim throughout this situation has been to protect the health of women with PIP implants.
"The refusal of some clinics to help their patients has left some of those women worried and confused.
"That's why we are running this ad campaign, to give women clear, definitive advice about what course of action they should take. I hope it helps women decide what is best for them.
"We have made it very clear to private companies what we expect of them - to provide their patients with the aftercare that they need and deserve."
Sally Taber, director of the Independent Healthcare Advisory Services (IHAS), said providers were affected by a "failure" of the Medicines and Healthcare products Regulatory Agency (MHRA) to detect the faulty implants.
The British Association of Aesthetic Plastic Surgeons (BAAPS) said it believes the implants should be removed as a precaution.
A poll of 230 of its members found 95% agree it should be private clinics and hospitals that should pay for replacement surgery for private patients, rather than the taxpayer.
BAAPS president Fazel Fatah said: "We remain steadfast in our recommendation to the public of precautionary removal of these defective devices.
"Although there is no immediate health risk, the gel within these implants is simply not meant to be inside the human body."
