40 minute wait to cancel contract

My contract expire 13 September 2015, and after waiting for 15 minutes on my cell for the cancellation department to pick up my call and allocate a call center personnel to assist me I decided to go in store at centurion branch and make my call from their telephones, little did I know that I was making it worse, today I just spend 40 minutes waiting for cancellation department to pick up the phone so that I can cancel a contract that is about to expire. <br> Then we decided to drop the phone and try again only for the next operator to tell me to hold on for the cancellation department, lets be fair now, after waiting for an hour for them to pick up the phone am I expected to wait again just to cancel an expiring contract?
