After literally being placed on hold for 30 minutes... Hello MTN

Hi MTN,

I'm trying to cancel My MTNChoice contract because I now have an MTN Supersonic account. Started at 083 135 Cancellations who put me through to Retentions. While still holding for them after 20 minutes I had to come and get assistance here.

I'd like to know what exhorbitant cancellation fee is going to need to be paid to close my MTNChoice account. Thanks!
