Vodacom is useless and clearly don't want their money

I am trying to open a new contract with Vodacom.I was informed there is an amount outstanding in my name of a contract I had 4 years ago.That contract was closed years ago with the settlement amount I received from Vodacom at that stage.Never have they sent me communication that anything was outstanding in 4 years. None the less I agreed to pay whatever is outstanding and gave permision for a debit order to go off. It was suppose to be done yesterday. So far the debit order has not been done by Vodacom.Trying to get hold of a human being in the accounts department is impossible.Trying to speak to an operator is impossible.I have tried every number on their site.The Bots and useless voice message promting you to enter cell numbers,ID numbers,to say something after the beep etc is the WORST waste of time ever and calls get cut. Could Vodacom please just have an actual operator answer your call when you phone.These recorded options and that stupid useless Tobi Bot is beyond frustrating and of no use.I want to pay my account,but Vodavon doesn't seem to want my money as I can't get hold of someone in accounts no matter what.Please please please please can someone from Vodacom accounts phone me.I can't believe thst you have to go through all that recording **** to get help.Please get rid of it and have an actual operator assist you.I am waiting fir your call.Otherwise Vodacom must never ask me to settle an amount because they clearly don't want the money or new bussiness.
