Unprofessional Service

Took son's car in for panel beating. Phoned after a month and left message for us to come and collect car. When son went to fetch car (I was out of town) we were informed that excess need to be paid before taking the car. My son was dropped of and had no other transport. I asked to speak to manager which was UNBELIEVABLE rude over the phone. I asked when they communicated about the excess as I'm away and can't pay immediately. I can play the message on my phone for evidence. He became so abrupt and threw the phone down in my ear. I then had to drive to a bank and pay money. Even if I send proof of payment over phone, they wanted it on e-mail. The end my son had to sit there for an hour before he could leave......
