Poor customer service

Firstly they changed my debit order date from end of the month to the 20th than after that it was the 15th making them have an extra charge of R65 if there is no money in my account for when they debit again. Secondly my new insurance made a call and put me through to Auto and General customer care to cancel my insurance with them and the operator immediately as I said I want to cancel my insurance with said "Ok and will get back at me". Dropped the phone and that was it. I wrote an email of cancellation to them and up until today no one has contacted me nor rep**** back. It's like they give you a run around when you want to cancel and I don't have time to be placed on hold for listening to the music at all and you are not going to debit my account as if I didn't notify you of my cancellation.
