iphone worse after being repaired - what can I do?

[Susanna Omynona]

My iphone needed repairing so I got someone recommended on this forum to fix it. The problem was relatively minor before but now it is overheating and keeps crashing etc etc. The repair person is going to try and fix it next week but where do I stand if they can't, and I have to get another or pay for someone else to sort it? Ive probably got emails or texts explaining what the original problem was but no other documentation from this sole trader.....

Take it to the chaps at Peckham market

I've always taking mine there and never had a problem
