VERY IRATE CUSTOMER

I recently logged a called via their WhatsApp platform . I was incorrectly billed . They advised me that I have upgraded my service ( fibre ) which I had no knowledge of. I am very disappointed with the service I have received from them . I was told on Sunday 03/07/22 that Someone from webafrica will contact me regarding my dispute . STILL NO REPLY. I AM HIGH FRUSTRATED as this large amount debited puts me off my pocket.
