Disappointed with MTN Superflex

I signed up for MTN Superflex, a great product by MTN, but feel let down by customer service and support.

On the date of debit order, my bank sent me a notification that there was a technical issue and my account, affecting debit orders. Anyway, I phoned MTN only to be told that they can't assist Superflex customers over the phone. I need to go to a branch. At the branch they needed my account number, which I never had. I called the Customer Care more than 8 times, no help.

I interacted with MTN via Messanger and logged a ticket on 03/01/2024, made several follow ups, only to get partial response on 11/01/2024 (despite a 24-48 hrs promise)

I was sent a link via sms, which does not work

Finally, on 11/01/2024, I received a link to make a payment funny it expires in 4 days

Most dismaying is that Customer Service consultant keep referring to the App, whereas the options are not available on the app
