billed for services that is already cancelled

Jan 2015 airtime subscription was activated on my cellphone number so I calles in RMCS to cancel it as I had never requested for it. After battling with them to have it cancelled, for over a month, they finally did at the beginning of Feb, I think. They called to confirm the cancellation. When I viewed my edgars statement for April, I realised that I'm still be charged for that subscription. They still charged me in Feb, Mar and April, R73 every month. Please note I was not receiving the airtime anymore.<br> I went to Edgars at Highveld mall in witbank last week and they called RMCS and confirmed that one of their consultants will phone me on Monday, 4th May. But as usual RMCS consultants NEVER call back unless you lay a complaint.<br> <br> I'd like for a reversal of these charges and my edgars account to be credited with the R219 that they're been taking from me.
