Pathetic Service Provider

On the 28/01/23 i called 10213 to check the status of my contract. I got so excited when i heard a voice prompt that said: "Great news, you are due for an upgrade" I was over the moon because i was eyeing the iphone 14 pro max. I decided i will go where i did my first upgrade; Istore Eastgate Mall. On the 29/01/23, i went to Istore Eastgate Mall to do an upgrade. I was attended to by Gift and i asked him to check whether i qualify for an upgrade. Gift went to the back office, i guess, and when he came back, he confirmed that i was indeed due for an upgrade. He helped me and was happy to sign my contract. He explained that i will pay R1289.00 a month and if there was any fee that i was to pay, the amount would have appeared on page 11 of 19. I then approved a debit order mandate of R1239.00 which also shows maximum amount that can be debited is R5000.00. First week of February 2023, my line got suspended and i called Telkom. I was told that i need to go in to the Telkom shop for assistance. When i got to telkom, they supposedly logged a call on my behalf and was told turn around was 72 hours. I got no response from Telkom and i called them and was told my call was closed. On the 28/02/23, telkom tried to debit R10329.00 from my bank account and due to insufficient funds, Fmb charged me R105.00 . I was told i have to pay that amount because i did an early upgrade. There was nothing that stated that i have to pay any fee or that it was an early upgrade. I then went to Telkom store jñ Festival Mall. The lady who was assisting me logged a call again. She informed me that the call was logged before for call limit. Who can at their right state of mind do a call limit of R10000.00? The lady at telkom advised me to go to Isrore and log a complaint with Istore. I then went ro Istorw in Eastgate to log a complaint. On the 15/03/23, telkom tried to debit again the amount of R11667.00 and the debit order returned unpaid. When a debit order returns unpaid, Fnb charges me R105.00. Telkom, stop debiting my account or else i will have to involve ICASA and my legal advisor. You can't debit more than we agreed upon I took back the phone that i loved back to istore. I lost almost a thousand rand for the accessories that i bought with the phone. Telkom is like one of those companies *********** customers. Stop debiting my bank account please
