I want my money back

I was charged R700 on a R250 package last year and ive been writting so many requests asking for somebody to call me back or refund me but nobody has bothered to contact me.i sent a request to a lady called Felicia who works for their HR who did respond to my emails saying they did respond to me but whoever told her dat was lying cos nobody has contacted me so she said i should log another request on their site but now the site is not allowing mw to submit the request. Rain needs to fix their customer service stinks this is ***** you cant be charging people for services they never used.
