Webafrica disservice nightmare

Initially I was happy with webafrica as I got good service. My nightmare started when I ordered a 2nd line. I had to pay 249 and the monthly premium was going to be 968. There was no communication from webafrica for 2 weeks. I then received an email saying my line would installed within 5 working days. I never heard from them again until they debited 400 from my account. Each time I call I'm told someone from billing will call me but that never happens. I must have called 10 times before someone said I'll be refunded after getting a call from billing to confirm banking details and the ever happened. In the meantime they attempt to debit 968 which I don't understand how they're debiting for a service I never received. The last person I spoke to was very rude and said there's no direct line to billing.
