A month ago we towed our car to a mechanic. Where we agreed that the engine needed replacing and it would take 4 days. All communication was done over the phone nothing in writing (yes this is wrong I know now). I did record some conversations but without him knowing ( I only started doing this when I realised that it doesn't look like it's getting repaired any time soon).
The first week he said he was looking for the engine and when he had got it it was the wrong one despite taking an image of the code on the engine to ensure he gets the same one - I haven't even seen this engine that he claims to have bought when I asked where it is, he said this is my address and go and see it, it's in my van. Then once he said he got the engine we went and saw the car hadn't been touched since we towed it to him. 14 days gone. Then he removed the ruined engine and since then I have been visiting him once or twice a week and each time a new story pops up, just give me two days or give me till sunday etc. And this continued for another two weeks (today).
4 days has become 1 month and the car has been left two weeks with no engine in, it's being stored outside with the windows down where it has started raining despite me telling him to close the windows where he specifically said he would and he hasn't (more lies). And since they are electric and then engine (incl battery) is removed obviously he can't close the windows.
I'm starting to believe he isn't going to fix the car at all. Too many lies and I need to take legal action.
Since there is no contract I tried emailing and explaining the agreement (in a very polite way in order just to get him to reply so that I have a contract - i.e I said we agreed 4 days, and money X, now it's been one month when do you expect to fix the car please give me a date). He didn't reply.
I have visited him once a week (minimum) since him taking the car.
What are my options?
He isn't really a registered mechanic either, he used to be VAT registered etc but not anymore.
