Pathetic after-sales service of WebAfrica

Absolutely pathetic after sales service. Biggest mistake was making payment, then it becomes almost impossible to contact them, unless its through Whatsapp chat, where the guy i was chatting with, decided to cancel my order, without my consent. And now i sit with the issue, of them not willing to cancel with the installer, so my alternate ISP cannot install. Ive tried all mediums to get a proof of cancelation, to no avail, so now i cannot have fibre installed, because they say they cancelled, but do not want to issue proof of this. I feel there should be a controlling body in place, to resolve such issues
