MTN bad customer service

I app**** for a contract on the 24th of November 2020 and up until today have not received anything. The last communication was a confirmation email with application number on the 26th and since then I have made numerous calls from one department reffering me to another then escalating multiple times. I'm now at a point after going back and forth on email were mtn says they cannot find my application even after forwarding proof of the confirmation mail. They asking me to reapply for deal that is no longer available
