Bad luck with mtn

Worse experience ever. I called mtn on 5 may 2021 to request for the itemised billing because I was going to need it in June the consaltend advised me to call them back in June because it only takes 2 to 24hrs for the them to send you an itemised billing. June has arrived now they are telling me different stories instead of me getting an itemised billing the billing department sends me a statement. I have have been calling for days they promise you haven and earth but no results. I'm still waiting for it even today.
