After sales support non-existent

Where does one start with this lot? They're quick to take your money to sign you up for a subscription, but don't expect any help if anything should go wrong after that. I signed up to a fibre offer they sent me last year, at which point they immediately debited my account. But the "service" has never worked. Have been trying for two months to get to the bottom of it via their stupid Whatsapp system, which is a test case in how not to offer client support. Does this company even have support? You can't email them. I tried phoning them but after waiting for 2 hours 27 minutes I gave up. Just Whatsapp - which doesn't work. So I'm sitting with something I pay for but can't use. DON'T USE WEBAFRICA. JUST DON'T. Try anyone else first.
