you have every right to claim from the original company that put them in, as they were negligent towards you, and this is whether they have ruptured or not, and you have every right to claim more then another op out of them. it is non-medical grade silicone inside you, and you had paid for what you thought was a medical substance, so you where mis-sold an item for the company to gain finical gain out of it.
all companies have insurance against things like this happening, and as they arent passing that on to you, then again they are being negligent towards you as a paying customer.
get yourself down to CA or a solicitor, and they will be able to help more, but i asked my uncle, whos a really good lawyer, and this is what he advised me (just in case i ever have this problem with my implants, and i asked him before mine got put in) xx
