Shoddy Service to Loyal Client

After being a loyal client for over 7 years with 2 mobile services, 1 was upgraded in Dec. 2021 and the other only added an airtime service which is due for an upgrade now, however I've been struggling with Telkom to approve an upgrade on the one number for which I have no device contracted. They treat me like **** even though my account is in good standing due to my credit profile being under Debt Review (Committed Paying off my debt (Credit card and loan) since March 2024 (I even got a letter from the administrator to motivate a new contract/phone but they refuse to assist). This should not impact my ability to pay Telkom as I've been paying my account every month. As soon as the other contract runs out at the end of this year I will cancel that as well.
