You Probably ddnt have money

Today is the 3rd of the month, my debit order date is the 27th of the month. Naturally if the debit order date falls on a Sunday, the next debit date will be the Monday but Vodacom doesnt know this. I called them and asked when they intented on debiting and was told a resubmission will be done, i called again and was told the same thing. Today the AVM calls me and threatens to disconnect my account, i called and Nompilo tells me they didn't debit because I PROBABLY DDNT HAVE MONEY IN THE ACCOUNT!!!!! After being on hold indefinitely for the Supervisor he also cant tell me why the account wasnt debited!! Vodacom has no right to me threatening messages when i took the liberty to call and begged them to debit me!!! ****ED for days
