Bad service with no where to complain

I'm really appalled with the service I'm getting from Webafrica. I had to sign up for a new line after being told I cannot move my existing line to my new place. when I get to the new place all I needed was connectivity and a router as the fibre line was already installed and used by a previous tenant. Now that i have to move again due to personal reasons they advise me still I cannot move my line. After being ignore by Vuyiswa numerous times on WhatsApp chat as that's the only way to communicate services with the company. she advised me i need to pay installation and connection fees. I'm puzzled cause they didn't install any line. i paid the connection fee which I now need to pay again because they cant move my service. Why must I be penalized for something I cannot control or change. i now need to pay close to R3,500 just to cancel the services. i'm also told that for my old line i'm billed in areas and that's not the case as i'm billed on the 1st for that month. if no payment is received they suspend the line for that month. now that my first product has reached its expiry 30 days i must pay again for May in June how they cant explain it.
