Unauthorised debit order

Cell C really gives the most disgusting service !!! My account for deducted for contracts i no longer have as my contract was cancelled two months ago as confirmed via an sms received and other contract phone was given back to cell c as there was a mistake made when i ordered a tab and received a phone and i had already returned it but yet they deducted from my account for the tab i dont have, also they charged me for airtime and data that was reversed and only th airtime was reversed . I demand my money be refunded or I will take this further. Its ridiculous that i have to phone around for my money that was taken without consent. <br> <br> <br> <br> <br>
