Incorrect Billing

I Have been a customer of Autopage for more then 10 years, and never had problems with them until this year. It is the third time this year that i have received incorrect billing and are being billed for services I didn't ask for. And when you try and phone customer service the service is poor. I had my phone in for repairs in April and asked on numerous occasions if there is any excess to be paid as i have insurance on my phone and repeatedly I was told there was no money to be paid for the repairs of the phone and yet 4 MONTHS later I recieve a bill for R1050 for cost to customer on my latest invoice, which has no description on it, just cost to customer. I phoned the customer service and they informed me, after spending 2 hours on the phone, that it was for the repairs to the phone. Which was fixed 4 months ago. I cant believe the poor service we are getting from as a Business owner myself, If i had to give my customers the service I am Getting from autopage, I would be out of business!!!
