Hi I received a LG V930 tablet for .99 on promotion when I purchased the LG V20 ..didn't even know it was a promotion when I picked up phone in store. Decided since it was November would wait and give it to our daughter as Christmas present. Well 2 weeks after the screen just crapped out. I have only had to use my insurance a few times in 20 years of ATT and it was handled in store each time. Can I just take this tablet back to a store to exchange ?
