No data

About a few weeks ago I purchased data via the app data never showed on my phone. The following week I contacted FNB because the money was taken from my account but no data shows on my phone they told me the problem will be sorted out asap that was on the 13th of December that I phoned. I only received an sms on Wednesday, 18th of December that they are working on the problem and it would be fixed with in 24 business hours. Until today (21/12/19) I still have not received my data or my money back.
