WebAfrica frustrating service and incorrect debit order

Rating of 0 was unfortunately not an option - Our experience with WebAfrica has been more than terrible. Hence us cancelling our services with them. We received notifications that cancellation was accepted and that it was given within the correct notice period. We were then asked to return the routers before a specified date otherwise we will be billed for it. We made arrangements for it to be collected however due to a no-show of their courier we decided to deliver it and were still well within the time frame given. We even received emails stating that returns were logged for both routers. A month later a debit order went off (money out of our account) to webafrica. They were quick to give an adress for delivery of the router however now that we are trying to get refunded we are told there is no accounts person we can speak to. They have NO telephone or email or address, ONLY whatsapp which is pathetic because you speak to a robot and once you get to a consultant you have to explain the whole situation over and they can't assist other than "escalating" the enquiry which according to them will take 24-48 hours. Now MORE THAN A MONTH later we are still no closer to a refund. This is more than frustrating and infuriating, and how a business can run like this is absolutely astonishing!!
