Swearing to customer

The owner of Yamaha tzaneen told me that I'm waisting his time because we haven't paid our bill with him, but the problem on our Rhino 660 is still not fixed and we won't pay until its fixed. As I walk in he started by telling me I'm waisting his time and that I'm ****ing with the wrong person so I responded by saying are you threatening me ? And he said yes I am. I've got the whole conversation recorded on my phone. He has a real bad attitude and I want something done about it and we want our rhino fixed the 4x4 and diff lock was working when we dropped it off now its not working at all. Its very unprofessional to swear at clients and I want Yamaha Sa to know about their branches bad attitude and swearing to clients by tzaneen branch owner.
