Disgusting billing

Telkom billing up to its same **** billing once again!! I have changed my billing date to my new pay date. I called and inquired the amount due, was given an amount to pay which i did, only to find my next bill was double the amount, again I called to query this and was told it was because i changed my billing date and first amount given was a pro-rata amount and the balance was carried over to the following month. I explained that i budget for a certain amount every month and was advised a note will be put on the system for a call back, which i haven't received. October I made payment on arrears amount as my service was suspended, my account is currently in arrears by 2 days as my due date was 31 October with my current amount. Telkom at the moment does not want to reconnect my services. This is absolutely disgusting, I am work during the day and unable to drop everything to sort out a telkom bill, that I will only be able to sort out when i have free time. Most creditors give their customers a few days to make payment
