Recently I purchased $2000 worth of gift cards from a person for $1400 cash. I verified the balance by purchasing an item with the gift card. I have the receipt for the $2000 gift card purchase as well as the receipt showing the balance after making the purchase. I went to a home depot store couple of days later and they tell me the gift card is not in the system? I called home depot but they won't give me any information unless I bring the person who purchased the card. I have the person's cell phone and email address and tried to get in contact but no return calls. I did a track on the cell phone to get the address (to send a demand letter), but the address leads to a deserted street. Where do I go from here? I'm willing to do about anything to get part of my money back. Thanks. This happened in los angeles california.
