MTN doesn't seem interested in my business

I have been onto the MTN business website to try and get Fibre to my business. There are no business contact details. You have to fill out a call back form, which I did. Two days later, no call back. The only sales number I could find on their labyrinthine website was consumer sales. I then sat on hold for seven minutes only to get transferred to corporate sales. They then put me on hold while they tried to find the correct procedure. Finally, after 13 minutes on the phone I was asked for the same details that I put into their contact form and promised a call back. I won't be holding my breath and they will certainly go to the bottom of my supplier pile
