bad customer

went to ford to get part prices for my bakkie. I was told when I arrived there by the sales consultant that he doesn't really want to help us as he has given us numerous quotes before and did not buy from him. I feel that as a ford client I can request as many quotes as I want and should I get a different quote which is more suitable for me I am not obliged to buy from this particular branch but can buy anywhere I like. In the case where this consultant stated that we do not buy from him after requesting quotes is untrue as we have bought there on a few occasions, we have had a previous incident at this branch previously where we ordered a part and after sending the consultant a clear photo of part and on arrival received wrong part. I have phoned Ford head office in re to this matter yesterday as well, we were told they will get back to us shortly afterwards. It is now 1 day later and we have still not received any feedback from Ford head office, and the best of all is that we bought our vehicle from Ford in CASH!!!
