Invoice dispute

I called Telkom on 28th July 2021 spoke to a consultant called Athenkosi Ngcenu who couldnt transfer my call to a superior neither provide me a turn around time for my query. She advised me that there is no TAT which i find very disappointing for such a big company. When i asked to be transferred she kept quiet and carried on doing other things saying that she is working from home and there is no one to assist me. The number i need assistance with is ***. I have been invoiced an amount of R202.70 that i need clearance with as i have been paying my account monthly.
