WebAfrica appalling service. Rip-off artists!

This companys service is appalling. I purchased an LTE subscription which worked ok for a while but then became so slow that I was no longer able to stream. After numerous phone calls ( normal answer time in excess of 20 minutes) I was told there is nothing they can do as Cell C do not have enough capacity. I thus cancelled my subscription on 16 May and receive conformation that the service would be cancelled on 1 July. I however was billed for July and now again for August. I have written to this ship of fools and phoned them but they continue billing me. The service levels at this company are the worst I have ever encountered. Be warned!
