Whats a reasonable amount time for a refund?

I would give it 30 days. From personal, and professional, experience it can take a while to get paper from one desk to the next. The guy on the phone RARELY has the credit card machine. Call them before you think about doing a charge back.

For example, I have dealt with one company on multiple occaions that takes minimum two weeks to check in returned parts at their dock. That's just how busy they are. Then the sales rep gets documents to turn in. Then he has to actually fill them out. Then he has to turn them in. Then the accounting dept gets the papers, then the credit card company has to let you have the money back. Not so simple. Then if you are dealing with a retailer, that's an extra couple steps.
