We ordered online a Rock Band set a month ago. However, after playing it the second day it made me sad to know that there was something wrong with the guitar. I first thought that it only ran out of battery but after changing the batteries, it still would not play. My boyfriend sent an email to the company about the guitar problem. He received a reply the following day with instructions to wait for the new set of Rock Band which they would send to us then return the defective set back. That was such a relief.
