Webafrica unprofessionalism and lack of proper customer care

I am so annoyed by webafrica, I requested their services in May 2021, and they delivered router as I already had fibre installed in my house. They said the line will reconnect in 3-5 days. It did not, I called them and they sent technicians to check it. They said my cables are damaged. I told them I am not fixing cables as I am renting I will return the router. They told me they will escalate my issue and they will get back to me. They never did, I had to go through their annoying WhatsApp chat where agents keep referring you the whole day and nothing gets resolved. Long story short, they keep on debiting my account even though their wifi never worked. I returned their router to sandton offices and I have email confirmation it was received in order. Now they are busy sending emails that my account is in arrears and they are sending it to legal. I always have to reverse their debit orders. This is unacceptable and very unprofessional.
