Extra Charges

The debit on my account runs on the 22nd of each month, but for the month of december i decided to make payment earlier (15 december 2017). My contract was due to run out that december but i opted for an upgrade which was then due to be debited from january 2018. But well for some reason their System (Vodacom) didn't pick it up (payment) because they still tried to debit my account on the 22nd (december) but they couldn't find any funds, then they started sending me sms' about my account being in arrears. I had to call customer care to sort it out ,after being sent from one department to another and vice versa. one of their agents gave me a ref number and assured me that the accounts department will look into it and rectify it, well that never happened because they still went on to debit my account (january 2018) for the new contract(which is fine) as well as the amount they tried to debit in december (including charges). remember i paid in advance in december but they still took my money for what they deem as december payment,including arrears which should've never been there in the first place. i called them again and i was told i had to send an email to ********** and use given ref (i ********** ) as the subject, and attach the payment receipt as proof. i did all of that (22 January 2018) and to this day, i'm yet to receive my refund whereas i was told within 7 days everything would have been sorted.

NOW TELL ME IF THIS ISN'T RIDICULOUS!!!
