Mtn lte uncapped WiFi not working

It’s my 2nd week having moved from Bloemfontein to jhb and I’ve called MTN almost everyday regarding my home lte uncapped product not working. They keep removing the barring and it only works for an hour or two. No one can seem to help me from MTN. I’ve called 135 so many times. Below is all the references to my calls: *** *** *** *** ***

Bear in mind I have coverage here and I’ve even went to their store.
