Poor service

In September 2019 I was contacted by Vodacom about an arrears amount, I told the lady that I do not agree as all debit orders went off. She advised me that it is a system error and will be fixed. Every month since then this amount keeps on coming back, every month I have to phone and spend hours on calls from one person to the next and each time I am insured that it will be fixed. Every time I have to pay for unlocking the lines, I have send multiple screenshots and bank statement to show amount went off. I refuse to send a statement where everything is exposed as there is sensitive information on. The statement i send shows the amount and the balance left in the account. every time i am insured it will be fixed and every month is a new story as to why it is there.
