No feedback nor calls to update on application

I went into into MTN Melrose Arch over the weekend to enquire about taking out a contract and converting from Prepaid to Contract. I have been with MTN for around 8 years. Our company has an agreed corporate discount arrangement with MTN and I provided all requested documentation.

I spoke with the manager Victor who promised to call me with updates as to the confirmation from their 'vetting' department. I have called their branch several times to enquire about the status of the application and every time the phone rings and when I do get through then I am promised that I will be called back.

Gentlemen, times are tough and a customer wanting to spend money with you should be welcomed. Can someone please call me to advise on the timelines, further requirements and why the service has been so poor?
