Slow customer care service

I recently upgraded from a 50/50Mbps fibre line to a 100/100Mbps line with Webafrica. 1stly the billing was incorrectly done. 2ndly I'm being billed for a 100/100Mbps line but an still only receiving a50/50Mbps line. I've tried to contact Webafrica about this for days and nobody ever gets back to me so that we can sort out the problem. Isuppose it's just anothe case of we have you money and ***** you if you care. Prove me wrong Webafrica.
