HHGregg  -  hh gregg’s stainless samsung refrigerator

I have a refrigerator that has a five year warranty and no one is responding to fixing my fridge. It is having a hard time keeping things cold in it. The repair number is not working and it should be a way to get a number for whoever took over repairs for HH Gregg. I am really upset and frustrated. My invoice # G599014447 please contact me at [protected]@yahoo.com. It will be greatly appreciated. S. S.
