Account Issue

After numerous failed attempts to sort out my Vodacom account I am still having problems.

It all started when I was erroneously billed for a second handset which was confirmed by Roderique Lategan from Vodacom. Apparently a credit was posted on my account for the months that I was billed incorrectly, but when I received my new statement for April it shows that I owe Vodacom an amount of R9 357.22 instead of them posting a credit my account got debited with a huge amount of money. This is causing me and my family unnecessary stress as I know I do not owe Vodacom 1 cent, so end of April I won't be able to pay my account yet again since this issue was not yet resolved correctly and then by the end of the day I will sit with a Vodacom payment for thousands due to them taking months to sort out my account
