Dropped a speaker off for repair (A child in my wife s class had broken the volume/input selector knob off) I was told 7-10 days to expect a call to see if the issue could be fixed. After 7 days I called for an update, they said they couldn t access my information. I wait till the ten day mark call again and am treated quite poorly over the phone. So after two weeks of hearing nothing I stop by the store and ask for an update and am told they speaker is non functioning. It was working when I dropped it off so I was concerned. I then had to inform them that the whole reason it was in for repair was because the input selector/volume knob had been broken off. They had no idea how the speaker they were trying to repair worked. That was highly concerning to me. So I took my speaker back and hope they didn t damage it further than it was.
