Seat Belt Related Problems of the 2004 Chevrolet 1500

Seat Belt problem

A few months ago 2 of the seat belts on the middle row seats of my vehicle became stuck so they are unable to be pulled out long enough to reach to be clipped in. Around 2010 several of the gauge needles on the instrument panel of my 2004 chevy tahoe started to stop working. From 2010 till 2015 I tried to take to a dealership 2 times to get it look at but by the time I took it into the dealership it would start working again so I was advise to bring it in when it was not working. A couple months ago when having the same issue I decided to take it to a local shop where I have paid $300 to try to get it fix, however the electrician found a report in regards to my car's problem and advise me to take my vehicle to a dealership to seek repairs at no cost. I then took it to ron tonkin Chevrolet on 8/10/2015 located at 122nd Ave and was told that no recalls were found for this issue just a notice and advised me to contact gm to seek cost assistance. On 8/11/2015 I called gm at (800)630-2438 and talked to a rep, then a senior advisor and was told that my request was denied and so I requested to talk to someone above the senior advisor. I was told that I will get a call in the next 24-48 hrs but since I didn't get a call I called them back on 8/17/2014 and was told by a supervisor that my request is denied because the Smart care coverage ended in 2011 and I should had follow the instructions on the notice sent to vehicle owner before 2011 to get my instrument panel gauges and seat belts repair. I explained them that I did not received that notice but they claimed that it was sent to me and for that reason nothing else they can do. I consider that this should be a safety matter and that gm should be responsible to cover the cost for the repairs.
