swearing at a customer

I went to collect my car which was involved in an accident on Saturday 21/11/2015. The insurance, I am claiming from informed me that any storage cost Will not be covered. I met a female consultant who told me that the cost will be of R 8439. I explained that the towing truck driver reassured me that the cost be by the insurance of the third person as she was at fault and that when he made me sign. He never showed me T&C at the back of the former and in term of the consumer act it was wrong. She expand that too ugh for bear their names, the towing trucks are independent consultants and they couldn't account for their actions. I agreed that I'd pay but wanted to speak to the manager. I introduced myself to him and asked if I could record the conversation for personal records. He stood up, got upset, started swearing at me. Whenever, I'd try to apologise be increasing the amount to pay by R 1000th. Finally said that I had to bring R30000 or he'll take my f** car away. Tried to push me out, asked me not to touch me because I was leaving their premises. He then came to my face almost hitting me with head asking me what I was going to f** do. I left & got the car with SAPS later
