still being billed for cancelled contract

<p>Worst service ever from you guys. I simply get no assistance from anybody at your call centres (that is when my calls are not cut). I have a data contract that was cancelled months ago yet i am still being billed for this every month. I called in last month 2/06/2016 call ref 1- ********** 4519, was told debits will be stopped & my money refunded however i have be billed by you guys AGAIN on 30/06/2016 (i have not yet got my money refunded yet you billed me again). Called in today 1/07/2016 spoke to Thabiso said he will call me back, he did not even ask me what was my reason for calling. Really pathetic service!!!!!</p>
