BAD CUSTOMER SERVICE / INSURANCE COMPANY

My vehicle went in for a 3rd party claim, I was informed the excess was R1750 and I accepted and paid for it in advance when dropping off my vehicle at the panel beater. When collecting my vehicle I get told I have to pay R2000 for my tire. I phoned Phillip he said i don't have to pay for it. A few days later he phones and says i do have to pay and refused to send this in writing to me. SAPCOR have been debiting my account with different amounts every month and he refused to send me a break down after over 5 emails and 4 phone calls requesting this. I then decided to cancel my insurance and sent 2 emails and then my account was debited this month causing my bank account into a negative. He refuses to answer my calls or emails still today. I still dont have my tire or an answer on why the debit orders changed so often.
