MONEY TAKEN OUT OF MY ACCOUNT UN-LAWFULLY

I have up-graded my Vodacom contract on 20 May 2015. Ever since then I have had problems with my account. I have asked Hello Peter to help me resove this problem. I was contacted by Vodacom and have now for three week been trying to get my money back into my account. Vodacom agreed that there were three amounts taken off my bank account in error. I have been told that a credit note will be issued. I was contacted by Vodacom today. They stated that the credits have been issued. I asked when the money will be back into my account, I was told that it will take anothert 10 to 14 working days!!!! This is totally un-acceptble to me. Vodacom was very quick to take the money, but when they have to give it back. it takes more than a month. I have had my contract with Vodacom for many years, but I am seriously considdering cancelling my contract. My husband is very overdue for an upgrade, but he is also considerring other options due to the fact that we feel Vodacom cannot be trusted.
