CAN'T GET THROUGH TO CONSULTANT

I opened up an MTN contract a while ago, shortly thereafter, due to financial circumstances I couldn't make any payments. The cellphone number has been suspended, and meanwhile I got another number. I currently don't have the number, and EVERY line, and number that I phone requires me to enter a number I DONT HAVE. I emailed customer care, but I have not heard anything back. How am I supposed to get banking details, and a statement to make a payment if I CANT GET THROUGH TO A CONSULTANT. This is absolutely rediculous!!! I will GLADLY give my ID number to get my number and account details. How silly is the answering system??
