This is mortifying, so naturally I've name changed. Not a troll.
Just over a year ago I chose to have cosmetic surgery. It's not a choice I'm particularly proud of and whilst I don't regret it, I probably wouldn't make the same choice again. I'm a very reserved person and not a lot of people know about it, I find discussing it and thinking about it really really embarrassing. I'm not 100% sure why, but perhaps in part because I feel guilty for spending so much money on vanity.
I had liposuction done on a common problem area and a popular facial surgery.
I did a HUGE amount of research and chose to use a surgery abroad, for lower costs. I deliberately chose a country that is under EU jurisdiction and also has very strict (more strict than ours actually) laws on surgery. (Czech Republic)
The surgery itself was fine, I was very uncomfortable before and afterwards (not during, as I was knocked out!) and the recovery period was long - 12 weeks in a compression garment in the height of summer, I'm an idiot and a wait of six months to see any results, a year to see end results. All of this is completely normal for the surgery.
But here's my problem - there are no results! My before and after pictures are practically identical, a few close friends have looked (cringe, cringe) and agree.
I contacted the surgery extremely politely with the before and after photos and told them there were no real results.
They replied saying that I had consulted with the surgeon on the procedure.
I replied saying that I was aware, and the surgery that was performed was the right surgery - but that the results were not satisfactory.
They replied saying that I had consulted with the surgeon on the procedure.
This has been going on now for over 4 months. They reply the same thing every time. I have quoted EU legislation to them.
I don't want compensation, I simply want my money back.
I was ready to give up as I felt that it was my fault for being so vain in the first place, but my friend said it was the same as if I had bought any service and not got what I paid for. It was not cheap (over £4k). She also pointed out that I underwent a significant amount of pain and inconvenience to be £4k worse off and "still ugly" 
AIBU to pursue a refund?
They have now said (after I said I wanted to resolve it without a solicitor) that they are "happy for your solicitor to get involved" so are clearly pretty confident.
TBH I have no idea what to do now anyway, as I've been very clear and firm over email.
