Cell C unprofessional service

My contract has come to an end in July, and am my account is still bn debited the same amount. I tried calling cell C for the past months but they call centre agents can't put me though to accounts department. Last month I receive an sms that cell c has double debited my account and it will be refunded. Our beloved cell c credited my account and debited it again with the same amount on the same day and I hv to bear the bank charges.

Like I hv bn with them for ages and I hv bn updating my detail with them, no cell c still hv my old personal details, so we call an update informing but they just give us middle finger coz after the call someone decides not to Save.

Bn a cell C customer has become a nightmare and today I call and was told maybe I updated my details with the other number and the one am calling from has not bn updated, like really that's bull coz all the numbers are on my name. Mxm am done with this network.

Cell C accounts department is not available but very active when they double debit our account nd also debit us for contracts that hs expired.
