dispute about this ****** telkom. idiots

well, i need 2 days to type this. On the 14th of sept i emailed to cancel my account because telkom raised my mbps to 100 and charged me R1058pm for this, and this without my concent. i was on 20mbps for R699 and then it went up to 50 for 800rand but now this. i called 10210 to billing to change it and they wont until i pay the full amount and once its paid, i can then lodge a dispute and they will credit me. still today nothing has changed. i paid the full R940 plus R140 for incurring interest, and nothing. now my internet line is down and no wifi for home even though i'm paying what i didnt ask for. ive sent emails and called and even gone into the store to try sort this out. i now want to cancel and go with Vox but they wont release my fibre line.
