cancellation of contract

I am so disappointed. I called more than 30 days(1st or 2nd week of March) ago to stop my cellc contract and switch it to prepaid. The system was offline and the woman said that they will cancel it and gave the details. I waited my 30 days, excited to get a new phone after my contract expired more than a year ago, just to hear yesterday that there is nothing processed and my contract wasn't cancelled. Now I have to wait another 30 days hopefully to hear it is cancelled. I understand that people make mistakes and that she just forgot, but then, don't do business at all when system is offline or have a proper book to write it down.
