ContractExpired April 2015 -still debiting account

Since I have had no luck with the call center - this is my last resort in urgent request for assistance!<br> I have had a contract with Vodacom.<br> I was told that the contract had expired in April 2015.<br> I have noticed that to date - my account has been debited.<br> No one has contacted me when the contract expired to ask me if I would like to cancel or renew my contract.<br> I have tried calling Vodacom to request all my money back and to cancel my contract with IMMEDIATE effect! but as usual no answer when contacting the call center.<br> Date contacted: 01/03/2015<br> Time contacted: 08/48<br> I have been on hold for 10 minutes!!! which i find utterly disgusting!<br> I would appreciate it if some one can get back to me so that this matter can be resolved ASAP
