billing mess despite paying on time

I moved to Cape Town from Jhb, I then got a new Adsl/telephone line but never received my bills. Then started receiving warnings that if I don't pay the amount due my line will be disconnected. Not having anything to go on, I logged into the website. Could see the amount reflecting against my Jhb account number. So paid it how I have always done with eft. Then i got a bill in the post even though I've configured my account for email. Didn't reflect the amount I paid previously. So I went to sea point branch and waited 2 hours. When I eventually got helped I explained the situation, we then figured out that I used the old eft reference number (but I never had a bill with the new one so it was honest mistake). I provided proof of payment and the guy emailed billing to sort it out. Today I was disconnected.. This after even paying their penalties fees the previous time. I've emailed the guy today that helped me before but had no reply. Tried going back to the branch but the queues are longer which means I'll sit there over two hours, not even sure why I should need too since I've paid my bills. At this stage I'm considering dropping Telkom altogether and going with a fiber provider
