No feedback and no service delivery

I received a call from Sizwe Msimango from Mobile plus, with an offer of R100.00 airtime pm,for which I only pay R39.00.The first Debit order went off in March but no airtime was credited in my accountmy airtime, I called ur support centre on the 21/04/2015 and spoke to an agent by the name of Phili who after confirming my cell number confirmed that there was technical error of which I never received any communication and was promised that airtime will be loaded on the 25/04/2015,which never happened! .After a couple of days i tried contacting the company via email but till to date no response has been received and still no service which means I paid for nothing..since no one is prepared to investigate and sort this, just terminate the contract and refund my money back, I just cant stand such an appalling service i have experienced as a new client with Mobilesplus
