Vodacom is about to give me a heart attack

In April I took out a data contract online and the amount was R349. Since then every month my account is a R100 more. They have agreed there is a problem with my account. But still no solution so every month I have to manually pay them the correct amount and beg and plead them to pass the credit. I have asked for my billing to be corrected and I am promised it will be done and yet here we are in July and still no correction or credit for this month.

They have said it went up because of the Vat implication which is nonsense, their prices include Vat on the website. Now they say it is a discount error.

Moral of the story....Fix it??? Or change the contact to the correct one.

Over 20 years of loyalty to Vodacom and this is the service you get.
