Telkom is pathetic

I have been having the worst experience with telkom. I have had a contract with them for years but from between the end of last year up until now, they have given the worst service ever. I have been calling every 2 - 3 weeks. I had been offered to top up my telkom mifi router bundle from 40gigs for R199 to 80gigs for R199. Yet since September last year....the bill has never been R199. And I have not recieved a cent back. September 2022 they'd deducted R223. Oct 2022 R289. November 2022 R295. Dec 2022 R376. Jan 2023 R382. Feb 2023 R385. Mar 2023 R364. April 2023 R250. May they charged R199. Debit order reversed many days later. Suspended my service. I made a manual payment via EFT, as the consultant advised me to do as it will reflect quicker. I paid R449. The R250 + R199 for the month ahead. On 02.06.2023 - they again deducted R449. I asked for a refund....which they advised they cannot do yet as it hasn't reflected on their side yet. Yet when I request invoice amount, it shows I have paid R449. They asked me to call back on the 15th....as it will only show on their side on this day. This morning I received my statement for June. R404.56. After calling each and every month since September asking if the amount will remain R199. And each consultant promising me that the amount will be R199 only. I have had it with telkom. I will go visit their store in canal walk as they do not answer their phones....and cancel everything. Please do not use telkoms services. As they are beyond pathetic.......
