Vodacom *****s your money when trying to buy data on app.

Do not buy data on the vodacom app! I made payment with my credit card and money was deducted immediately. Right after my money was deducted I received this message : "Error. There may have been a problem while processing your payment" I have contacted the customer support via the email the provided- no response. I contacted two other people via the app, they are unable to help. Said they will escalate the matter. I made two transactions of R490 each with nothing to show! I need this to be sorted ASAP! This type of service is unacceptable. When I buy data Via the FNB app, the data will ALWAYS reflect immediately.
