Debited for 2 accounts that I don't have

On the 1st of April 2015 I noticed on my bank statement that I have been debited a total of 4 times for Cell C accounts.<br> <br> To my knowledge I only have 2 Cell C accounts which are fully paid and should have been debited.<br> The other two accounts in querie are *** and *** in the amounts of R153.99 and R114.99 respectively.<br> <br> Both of these accounts are not being used by myself, and Cell C is more than welcome to do an audit on data useage and or phone logs to prove this to themselves.<br> <br> What is even more concerning, and bordering on ********, is the fact that I changed my banking account details on 17th March 2015, and instructed Cell C to amend my debit order details for numbers *** and *** only. I am therefore alleging that CellC has **********ly debited my account in the above mentioned amounts, and am seriously considering further action, just to prove a point.<br> <br> My challenge to CellC is two fold:<br> a) To prove that these phones are being used by me<br> b) To provide me with the necessary authorization to debit my account for all 4 accounts<br> <br> The required outcome of this complaint would be the refund of the monies **********ly debited from my account
