I've had a nightmare with my Bongo

I found a man on ebay who took the car away on a trailer and said he would fix it, but four months later I am now having to pay to have the vehicle recovered back from him as he has done nothing with it other than ask for more time and offer excuse after excuse.
So I would like to know if anyone can recommend a trustworthy place where I can have my Bongo recovered to that will source and fit a new engine for me? Otherwise I think it is going to be expensive scrap

Any help appreciated.
