Shocking Billing department

I have been battling for almost 3 months to get my Telkom billing problems resolved. Telkom created a new contract on my account instead of upgrading my existing contract. After many weeks of disputes the invalid contract was finally removed. Telkom still billed me for the new contract, the existing contract plus the upgrade contract. After some more disputes Telkom verbally told me that there have been a credit for the invalid contract. I payed the invoice amount minus the credit portion and then confirmed with Telkom support that my account is now paid up to date, this was on the 10th of October. On the 31st of October my account was suspended for non payment... After phoning support Telkom support concluded that the system shows arrears but in fact my account is R5 in credit... A new dispute was logged, that will take between 7 to 9 days to resolve. So I have paid my account but I cant use my phone... Telkom wakeup and sort out your billing department!!!! last case nr: ********** 9
