MTN - your website is takes my money, but does not give data in return!

I have been a customer of MTN since 1997, and have recently received terrible service. I tried purchasing 5 gigs of data for my student daughter on the MTN Web on 8 June and 10 June 2020 for R199.00 each time. The transactions failed, no data was received, but my bank account was debited for R199.00 on both attempts. I called 135 and eventually received a ref number on 1 July. Every week i call to follow up, holding on often up to 25 minutes at a time, to get told something else every time. Today i called again, asked to speak to a manager and got cut off. I will not continue like this, i am sick and tied of this poor service which is costing me money, time and frustration. I am still out of pocket by R199.00 X2. The ball is now in your court, lets see how you are going to react!
