MTN - moving from contract to prepaid

On Monday I contacted MTN to move my mobile number from contract to prepaid (As October is the last month of my 2 year contact) and due to financial constraints I can no longer continue my contact.

The initial contact with MTN went smooth, but shortly after the phone call (give or take a hour) I noticed I could no longer access webpages on my mobile even though I have data and LTE/H+. Also it keeps prompting me to login to a MTN network. I can make and receive phone calls.

I have now contacted MTN 3 times to try fix the issue. The 3rd time I was told that my issue have been escalated to a manager and I should receive a update/fix with 24 hours, that was yesterday morning and I have still not received any help.
