Webafrica **** service

i have been billed incorrectly by wed Africa i wrote to support 7days ago and was told that my bill was updated. when i woke up this morning i realized that my fiber was suspended. reaching out to them on their WhatsApp support line is almost impossible, i was put on hold for over 4 hours, talking to over 5 different agents, and having to explain myself over and over to each and everyone of them they will transfer me from department to department, the advise i get from their agents is that i should pay for the whole amount and they will credit it back to me in the next month. otherwise my Wi-Fi will not be activated. i am billed for a service fee that i already paid for, then they tell me to risk paying again, what kind of nonsense is this?
