Double billed account and refund

Vodacom, thank you for NOTHING. You double billed my account (as with thousands of other customers), on 31 December - sent a plattitude sms apologising and stating that you would refund by Monday earliest - including all related bank charges.<br> No surprises then, when the refund eventually reflects in my account that it DOES NOT reflect the bank charges for the debit order. Not one cent extra!!<br> <br> Please ensure that these charges are refunded, as promised, PDQ!!!<br> You would be very very quick to cancel my number, black list me etc, if in your opinion my account is in arrears and yet you can double bill and not refund the full amount.<br>
