The other day, I was taking my defective Droid back to Wal-Mart ($100 cheaper than at Verizon or Best Buy) for a replacement. Before I went into the store, I took out my 16GB microSD card so that I could exchange it for the one that comes with the new Droid. The woman at the counter tried to tell me that I needed my contract in order to do the exchange. Not understanding why, we argued for about 3 minutes before she decided to look at my receipt and saw that I payed full price for it. The woman apologized and proceeded to examine the device. I explained to her how to remove the battery after a few seconds of watching her struggle. Her excuse was "That's what I thought, but I didn't want to break my nails". She tried to do some stuff on the cash register, then called for a Costumer Service Manager to come back. We waited for about 10 minutes, then she called again. The woman asked if I had the original credit card. After I explained that it was a gift and that I was out of town, she tried to tell me that there was nothing she could do without it. Cutting to the end, it took 4 people over a half an hour to work the cash register for the exchange. Through all the frustration, I forgot to mention that I still had the old MicroSD card (got out with 2 16GB SD cards). I remembered later while I was doing some grocery shopping but decided not to do anything about it. Some friends of mine say I was wrong for not saying anything. What do you guys think? What would you have done?
