Telkom fibre contract upgraded unilaterally, without me knowing. Now I am in arrears and suspended!!

I have uncapped Fibre contract through Telkom (20 Mbps). They UNILATERALLY upgraded my contract in November to 50 Mbps. I did not ask for this upgrade, I was not informed of the upgrade. I normally pay R 1000 for my 20 Mbps contract monthly. Yesterday, 8 Jan 2021, Telkom suspended my service due to me being in arrears with about R 1500. This is because I've been paying my R 1000 for my 20 mbps contract, instead of the R 2200 for the new 50 mbps contract!!!. I am an IT project manager who has been working from home due to Covid-19 since March 2020, which means that I now cannot work. I'm being sent from Billing dept to Sales Dept, and each blames the other. I cannot speak to a supervisor because everyone is working from home. Now been waiting for a Sales dept supervisor to phone me for 16 hours, and nothing yet. I logged a complaint with ICASA and told them about it, but no one cares, now logging on HelloPeter and hoping that this will escalate the situation. ICASA complaint number: CAS-128270-R0B4V2.

I was on the phone with Telkom for 6+ hours on the 8th of January 2021, I spoke to about 8 persons in both their Sales and Billing department, and still not resolved.

The best of this yet: My close friend's ex had EXACTLY THE SAME ISSUE THIS WEEK.

SHAME ON YOU TELKOM!!
