Billing is not rocket science! Cellc *****s money

Highly upset with the billing process at Cellc. So unprofessional. My dad has a contract with Cellc but i use the phone. We advised Cellc we want to change the banking details to mine and not my dads anymore.<br> <br> I sent the documents required to do the change. End of April Cellc deducts R756.98 from my account......6 days later R278.99. In total this adds up to R1038.00 HOW IS THIS POSSIBLE? The contract is only R400 a month?<br> <br> That's not all, Cellc deducted R400.00 from my dads account as well. So please explain where you get your incompetence from. I want to stop this contract as soon as it ends and i will make sure everyone hears about this service. I want a REFUND!!
