Pathetic service

I have 3 contracts with Vodacom. At the end of September my account was not debited so I called to let them know - they suddenly double debit my account. After calling numerous times and requesting a manager from the collections department to call me back so we could resolve their issue, no call received until today. In October they didn't debit again, so upon calling them yesterday I was told that they tried debiting my account on the 29th and there was insufficient funds available yet I received my salary on the 28th - I was even told that my account is now in arrears. What a big ****** joke!!! Pathetic service...I WANT A COLLECTIONS MANAGER TO CONTACT ME TODAY THE 4th November 2021 by 3pm to resolve the issue which now put me in the credit bureau as a slow payer....
