Service issues and problems when trying to get a new contract with MTN

Good Day

Please explain to me why it is so damn difficult for me to open up a contract with MTN, they are not activating my line or someone is not doing there job as this has been open and sent to multiple service requests and stages but nobody can work out what is going on when it comes to downgrading from an original package to a lower package, i find this very frustrating and if this is how MTN is like when opening up a contract, then should i expect further issues with MTN. This has been going on for days on end and nobody can explain to me when this will be sorted, please help urgently with the credit vetting department. I see there has been a lot of complaints . Thanks
