Not Bothered to Respond

I called MTN Corporate *** four times this week and have received 3 different reference numbers. I have sent 3 e-mails requesting information and to date have not received a response. I have a phone on prepaid and enquired about porting the number to MTN and taking out a new contract. I have requested a list of all the current specials and also a breakdown of the monthly cost, including the discount I would qualify for in terms of the scheme between my employer and MTN. I have only received the port application form which was emailed to me by Bytes Admin. MTN obviously doesn't need any new clients??? I'm absolutely frustrated with the non-response.
