Vodacom is **********ly charging customers

I have settled vodacom the outstanding amount of money when I was cancelling a cellphone contract I had with them. They advised that they will deduct the last premium from as I had canceled after the monthly invoices were printed. Last month they deducted their money but today I got an email advising about this month's invoice, which means they are yet to deduct again. I'm fed up with vodacom prejudicng the customers livelihood. Why is this company treating customers as a cash ***. If this months debit order goes through. I'm opening a case to the police. I have settled the outstanding amount they have deducted the last invoice without consent last month. What is this nonsense ******** **** your vodacom wants from my money. Please stop this **** stop deducting money from my account I paid your phone off. Why are you doing *****
