Dissatisfied

The banking app is nonsense and when you request a call back it takes forever, I've used my own airtime to contact the customer service the lady was clueless put me on hold for more than 5 minutes. Then today as expected I was disappointed again I had to call again this time about the money send issue had to call twice the 1st consultant couldn't access my account because I couldn't receive the prompt ,she put me on hold then told me to self service Reverse the money I did it she said it's a technical issue. 2nd consultant said I should try after an hour I tried sending the money after 2 hours still had to Reverse the money because no notification was received even after waiting 30min of grace period , she blamed it on my phone because of dual sim saying it's the clash of the networks ... I'm beyond disappointed the fact that I had to call customer service 2days in a raw it's really ridiculous,please educate your consultants
