WebAfrica charges without connecting your internet

I was quite excited to find a company that only charged once they provided you with internet access (or so you claim on your website). However this morning I woke up to find my account had been debuted, and not a prorata amount (which is to be expected seeing as we're more than halfway through the month), but more than the monthly premium I signed up for. Yesterday the technician installed the cables and advised that I called in to have my router delivered, however it's near impossible to get hold of anyone at WebAfrica.

Since yesterday I've made numerous phone calls and spent more than 40 minutes waiting for someone to pick up the phone at your call center, I have tried your "call back option" - but no response there either and the Whatsapp service is a joke as the "bot" is no able to provide any useful assistance.

So now I'm being billed for internet I don't have. This has not been a good start to what I'd hoped would be a long standing relationship, so please could you pick up your cables and refund me my money. If this is how you treat your new customers then I'd rather cancel the agreement.
