Telkom Billing F*ck up as usual

so i get my bill in september and see it higher (R1500) then usual, it deducted from my acc on the 26th of September which I left as to avoid the pointless phone calls. so this month my bill is over R2000, and knowing my bill would never be over R700 max i went to check whats going on. turns out the claimed to have never received the September payment. So i phone, and Complain, the consultant i spoke to insured me that it would be fixed and i would receive a message to notify me when it is. today 2019.10.07 i get a message saying my account is blocked until payment. i phone again, and every damn time there is a new excuse. i really do hate the frustrations coming with taking out a contract with telkom. i need this fixed, IMMEDIATELY! if end of the month they deduct more than they should i will dispute that and pay only my normal bill. and o help you if you charge me for it!
