Horrible services

I had a problem with my car and I was refered by a friend to Gearbox and diff centre I called and explain my problem to Vince, he didn't explain anything but said I should bring the car to their workshop I brought the car into their workshop. He(Vince) was not helpful but I saw an arrogance of him. For the first time I went there the picture of their service he displayed to me was very bad. I asked him if he can assist us because battery of our car is flat and the response to me was I need to get mechanic to check what is the problem and he didn't intend to help me anyway I then borrowed some spanners to change batteries he gave me spanners but that didn't work out, I then told him the problem but he told me that, it's not his problem they need the car's motor to be running then they will test it. Refered me to closeby auto mechanic I went there but they could not help me because they were very busy. We then saw one of Gearbox and Diff center mechanics and spoke to him he was helpful he even check the battery if it's gonna charge if they put on charge in their workshop they find out that the battery is finished and we need to buy a new one and he advised us about the closest auto spares where we can purchase new battery. We bought new battery and the car started then mechanic showed us where to park the car and give car keys to Vince. Vince told me that he was gonna call me and I waited and he never call me after 16:00 I called him he said they gonna test the car the following day. I just wanted to know what is the problem and how much is it gonna cost me. The following day Thursday 17/09 after 12:00 I called him because he didn't call me as promised he told me the mechanics have tested the car but he was waiting for them to give him the report. Since 12 until 3pm i have been waiting no word from them I called him he told me that gearbox chain is broken and change in gearbox speed is faulty he is just waiting to get parts prices then quote me. How much does the phone call cost for him to call me and update me about everything? Does he treat everybody the same way? It's a very disappointing service from the frontline staff.
