I don't really know where to turn with this so maybe somebody on here will have an idea.
Last week I sent a building inspection report to my builder with several defects that need rectifying along with a registered letter asking him to supply fittings he had not supplied as per the contract. Last night he sent me an email asking if he could drop in today to look at the hot water heater which is making a strange noise. In the course of the exchange of emails it turned out that he wanted to look at "other things" though when I pressed him for exact details he was evasive. Finally he told me that he would be attending with a witness - his wife. I had already told him that I wouldn't be prepared to discuss any issues face to face with him and from now on I won't accept anything from him that isn't in writing. I don't understand his purpose in having a witness. Is this normal? He has now rescheduled "pending further advice". What does that mean?
