paying for no reason

I have had it with vodacom last month I put money from my mother's account from standard bank on the 27th which I know the money will collected the following day now the people from Vodacom did not collect the money on time and now they are blaming the bank,I have spoken to people from the bank and they told me they are a 3rd party in this whole situation. What passes me off is the fact that I have to pay the amount of 950 instead of 575. One thing for sure I will never recommend anyone to go and get contract from vodacom, you do not take care of your customers. I fail to understand why I have to pay for some **** mistake you assholes made,I really regret taking a phone with you for real. I had contracts with Cell and MTN I have never expirience such thing in my life.
