Shocking customer service WhatsApp Support and continued incorrect billing

Worst customer service ever. I relocated from CT to Krugersdorp in Dec and requested a home move of my fibfe line in Nov last year in advance of the move. Yesterfay I was STILL billed for CT fibre line for Feb 2022. I have not used that line since mid December 2021. This is theft! But try getting this reolved via Webafrica's totally useless WhatsApp Support Chat., ive been trying unsuccessfully since Nov!
