I rocked up, no appointment, with electrical problem.
Peter did complete check of problem, fixed it, (even though no parts were used), taking a good hour, and did not want to charge a thing for his effort, expertise and time.
I managed to make him accept a token amount, so all in all, very happy with their prompt service.
For any future such problems, I will certainly be giving them my business, and insist paying the proper and reasonable amount.

Thanks guys
