I signed up for Amazon Student a little while ago, getting six months free of Amazon Prime. Somehow in the next five minutes, I canceled the free trial and started up the discounted Amazon Prime service ($39/year), according to the customer service.
I obviously wanted my free trial back so I called them up and told them the situation. The guy originally said that he could not give me the trial back (that it was impossible) and that the only way to get my 39 dollars back was to cancel the service, that, too, I did not want. I basically thanked him for helping me, and was about to hang up when he asked if he could put me on hold and talk to his supervisor. He came back about five minutes later saying that he was given the go ahead to not only refund my 39 dollars, but give me a year of Prime free at that 39 dollar price.
Now, while the guy didn't seem to happy about that (if he didn't want that to happen he shouldn't have said something) and made sure to remind me that they don't normally do this, but I'm happy that his supervisor helped me out.
