Appalling customer service

I had my rain sim and router delivered on the 3/8/2020. They told me it would take 2hrs to activate my sim. I waited the entire night. The router did not work or pick up a stitch of signal. I email rain the following day. I got a ref number that stated I would be called in 24 hrs. I have done this several times and I am now sitting with multiple ref numbers. No one has contacted me. When I call rain I there is a automated voice message. Their call center is closed and the offices are empty. Today is the 11/8/2020 and still no feed back. The R700 however was successfully deducted from my account. I want to understand why they are selling routers and sim's when they know they are not providing technical support. There is no one to assist me and my money has been taken. i have even left email telling them I want to cancel and they should collect the router and sim. I do not know what to do because at the end of this month they will deduct my money again.
