The most pathetic service EVER!

For 10 years, I have been a loyal customer of Telkom Mobile. I have done all my upgrades with them and even an early upgrade which has been a total nightmare and the most pathetic service I have ever received from any service provider. In June 2024 I app**** for an early upgrade with Telkom and they informed me that I would be required to pay an additional R500.00 per month for the following 5 months as a penalty fee which I obviously agreed to and had to actually end up paying R800.00 per month. After the 5 months was up, I went back to Telkom to query whether I would still need to pay this amount and they said no. I kept getting sms's and emails informing me that my account would be suspended if I did not pay in additional money every month. I paid in the money every month. At the end of April I noticed that they have increased my debit order from R2081 to R2881 and I believed that this would cancel the fact that I would be required to pay in monthly. After all of this, I received an email this morning saying that my account is suspended due to non payment even though the debit order for R2881 went off on the 30 April 2025. I called them once again and they requested that I pay in an additional R177 to keep my account on. The reason is because I have reached my spend limit. When taking out a contract, we as the customer believe that the contract amount is what you are required to pay on a monthly basis with no hidden costs added on later. This is extremely frustrating and annoying as I am not wealthy and I work on a strict budget monthly. I need Telkom to rectify this mess up urgently. I have tried calling on numerous occasions to get this sorted out but nobody seems to know how to assist me. How does a business function with *********** staff and management???
