time for legal?

After having BA in june 2013 with 300 mhp partial left breast 'bottomed out'.  I was offered free pocket revision which I had in April 2014.  After op extremely painful and implant felt mishapen (lumpy at the bottom) and on 17/05 internal stitches 'popped' or gave way and the implant has now dropped back, with terrible rippling all around the implant. 
Had 6 week post op with PS (mr netri of Transform) yesterday 29/05.  In the appointment he agreed that the revision had been unsuccessful but then posed me with 3 options.
A. to have the revision again but giving the fragility of the tissue inside my breast there would be high risk of failure again.  B. replace implants for TFS/TFX (which I was never offered the use of at my initial consultationin 2013) which would be fuller and get rid of rippling, however there would be a risk of the implant 'flipping over'.  C. (which Mr Netri advised would resolve problem fully without doubt) replace remove and replace both implants and do uplift (which on my initial consultation in april/may 2013 he advised was not necessary as i just needed 'filling up').
I was then handed over to the co-ordinator who advised option A would of course be free,  option B would be the difference in cost of implants £500, then option C I would be charged for removal, new implants and uplift at £3500.
All this bearing in mind i only have an issue with my left boob.  I am absolutly astonished that they feel that they can put me in this position as i obviously want them to be right but feel i will have to settle.  Would it be time to get legal advice as I have done nothing wrong.  Granted the mhp warranty does not cover severe rippling but surely the  company has a responsibility to its patients to correct 'faults' with operations at no cost.
Any advice from anyone would be greatly appreciated, feel as im stuck between a rock and a hard place.  Please help.
Thanks
