Vodacom must be bankrupt that’s why they are robbing their customers

I called 27 September 2017, querying the amount on the app regarding my account. Was told it is not updated and was given the correct amount, which was less. August I get another statement and I again call (27 September) to query the amount as it is higher. Spoke to Selloane in the Solution department and was told they will write off the charges. Was promised a callback and never got one, and nobody left a message. Nothing was done. Now again there are charges for using data, which I have not. Are you bankrupt, that you now have to start steeling from your clients. I want this sorted.
