samsung Refused to honor their warranty on their tablet dallas texas

I purchased a 10inch 32g samsung nexus tablet as 1 of my daughter's 2013 Christmas gifts. It nearly costed $400. It stopped working before it made 5 months old. I contacted samsung & after I gave them all my info, the tablet info, they requested a copy of the original receipt. After faxing the receipt to them, they denied ever receiving it. I then mailed them a copy & returned to the sam's club that it was purchased from and had sam's email & fax said receipt. I was eventually contacted by samsung after i had placed Numerous calls to them, in which weeks had passed. I was told that my warranty had Already expired before i even purchased it from the club because sam's had been purchased the tablets from them. I advised them that as the consumer, I am aware that I had a year after my purchase for the samaung warranty. Back & forth with them for almost a year, leaving me on hold for over 40 min at a time, transferring me over 7 times each call, i had enough. I then contacted the BBB & advised them of Everything that had been said & done. The BBB contacted samsung & were told that they will now repair the tablet. I told the BBB that they were Not telling the truth. I told the BBB that I no longer wanted the samsung tablet & that I wanted ALL money spent on it returned. Samsung told the BBB that they would honor my request.... Well, they LIED...AGAIN! placed many calls to samsung for months again!!! I then contacted the BBB again. After the BBB contacted samsung again, samsung told them that they will refund my money. After months passed i mailed the tablet back to samsung with the requested receipt & serial number. Samsung LIED AGAIN!!! They attempted to repair the tablet & damaged it even more!!!! Now i own a broken $400 tablet that i can do nothing with....I Promise I will NEVER buy Another samsung product in this Lifetime!!
