Bad service Cell C - canal walk

Good Day

On Thursday, 28 March i went to Cell C (Canal Walk)to advise them to change my banking details from which my account gets deducted. The consultant (Vaughn) advised that they will change my account details, however, March and April’s billing will still come off my old bank account. The deduction will only come off in May on my new account. He mentioned that in the meantime, i pay the R372 via Pick n Pay and provide him with the receipt. Which i did.

On 30 March - i received a sms advising me that R742 came off my account for Cell C.

Kindly advise why i now have paid Cell C thrice for my account? (Once via PnP and twice via debit order which was only to come into effect at 1 May 2019.

I expect feedback on this. Please contact me on ********** 776 or **********

Thanks Shanaz
