My line was cancelled without my request

I'm livid, on 23rd November Vumatel sent me an email to advise me that I've submitted a request to have my internet moved to a different address, I have never requested this and have not moved house. I called Afrihost customer services line and used their whatsapp services, I've had endless conversations with their agents who promised they "spoke with their managers" and the issue would be corrected and I would not lose my service. Today 1 December my service was cancelled. I called and whatsapp them this entire day, sent POA and still nothing! I work from home and I'm fuming, they don't have an after hours number or service, it is now after 7pm and I cannot get to speak with anyone. Their service is a useless!
