Independence Audio-Video

I miss an appointment so I had to pay the full balance in order to get it done, my bad so I took it on the chin. I asked for the bass knob to be installed they said yes. Pick my car up no bass knob and the guy was rude like basically we don't do that unless you specifically asked for it (which I did). Had my own Amp, radio and speakers. All that was needed was installation. I ended up selling the car but before I did had to take my music out then I see it! They just threw it in my dash. No radio dash kit just a face. Radio riding loose as hell the whole time. I paid 500 and changed for this service, never again!
