Elite Mobile - no help

My SIM card had been deactivated (25 March 2015) due to the negligence of elite mobile, as they were not taking money out of my account but continued to supply me with my monthly airtime (contract). I had paid the amount and sent my proof of payment with no response. I had called the custom care line +-8 times till I got help saying they have received my proof of payment and delivery will be within 7 working days. with no delivery being made, I called back another 4 times
