Yet another bad experience

On the 2nd of October I received a message stating that I need to pay my account as my line will be blocked, I immediately phoned Vodacom and the consultant advised me that my debit order has been canceled and I need to pay via EFT, I did exactly that and the debit order went off that night. Phoned the next day and was promised a refund of the amount I did the EFT for. This morning when I checked up on the progress I was advised that they won't be paying the full amount as they already took it for the next payment thats due at the end of the month??? It was not theirs to take to start off with! I have a set out budget and due to go on Holiday with R3200 less than I started with. Now nobody wants to assist. Canceling all my lines!
