No Service, no aftersales, no feedback

Called webafrica to find out what is the problem with my slow internet connection and they told me that they don't support Cellc anymore and I must please move to Telkom, this process was done great but then the issues started they debited me for my cancelled package R 530 and debited me for my new package , called them and was told they will refund me asap her nothing no refund after following up 10 times. I was told they will come fetch my router with a courier service witch never pitch in more than 30 days after they confirm with me they will send them no apologies from webafrica. Month end come still no refund for the R 530 incorrect debit. Best part of it all I get debited for the router which was R 1928.00 for not returning the router , so called them and said that the courier never showed they apologised and said they courier company will come the same day it has been 4 days later and no courier company and no call or refund from webafrica. This company is great at selling but has no aftersales service or support and take no responsibility , The billings manger is never in according to staff after I hold minimum of 30 min for her there is no answer and you get told she will call back. This is the worst service I ever received.
