Vodacom's technical glitch

I received a message from vodacom advising that the debit order was unpaid. I phoned customer care line to rectify this problem and was put through to the accounts department. I spoke to a rude lady with so much attitude from the start of the phone call that advised me vodacom had a technical glitch and I must go and pay my account and the nearest vodacom branch. When I told her that it is inconvenient for me she smirked as if was my fault and I was taking up her time and told me it will then be debited on the 2 October, because vodacom doesn't know when this problem will be rectified and continued to advise me to go and pay my account. She spoilt my entire day making me feel as if I don't pay my accounts and even asking me if I'm sure I have money in my bank account
