Telkom unable to resolve Credit Limit Issue

Hi, Help! My account details below. My account with Telkom spans more than a decade and recently I’ve missed my deadline on installment due to bank changes. However, I’ve paid my account because I use the mobile for business purposes. Problem statement: No outstanding amount for 2 months but my service is disconnected monthly for 2 weeks. Currently, for the past 2 months my service had been disconnected even though my account is up to date. Unbelievable right? I do not owe Telkom any amount and I’m still disconnected because my “credit limit” is now zero. I requested this to be rectified 2 months in a row where I’ve been disconnected for 2 weeks at a time and there is no solution since my credit limit is zero. I requested for my contract to be cancelled but that is not an option. So I must now pay R3100 monthly for my service to be disconnected 2 weeks every month until my credit limit is “fixed” not sure how. I do not owe telkom monies and not having a service is unfair. I’ve tried all avenues at the call center and telkom shops to no avail.
