What Is The Average Time For A Accnt Cancel Refund To Be Received?

I cancelled my Mozy account in Sept 17, 2014 right after I was charged more than $750.00 for a full year in advance. Since I can't really afford the service that I had been using for several years, I decided to cancel the account and request a refund for the unused portion (maybe a day). I was told after cancellation confirmation that the refund would be processed in 1 or 2 days. It's November 3rd and I still have not received my refund. The agent that contacted me for the cancellation says they 'are working on it', but the fact of the matter is: " how much longer should I wait to receive a refund on a charge that's already adding interest and finance fees in my bank statement?"
