Worst service ever

Absolutely the WORST customer service ever. I have been sending messages via Facebook Messenger since 5 June 2020 to settle a cancellation. My husband and I got married in June, and we have no need for two routers, therefore the cancellation of this one. I am currently still a client of this business, but seriously rethinking it now. Ref nr received for cancellation CAS-111650-M2Q2M2. Every TIME someone gets back to me, they say they will follow up, and get back to me, but as expected, NO ONE EVER DOES! We are having trouble getting your router back to you, because it seems like RAM COURIERS are supposed to pick up from us, but still they have not contacted us to arrange this. Monies haven't been debited for June and July, but suddenly Sept comes, and R399 gets debited for a service that we don't even use anymore. It was supposed to be refunded within 7-14 days after I complained, and of course no money has been refunded. But I will keep on demanding this refund!!! I received a courtesy call earlier this month to check if I am happy with service, and as I explained to that consultant, I am highly dissatisfied with your service... He also was going to get back to me, and obviously, never did. This is horrible client service.
