Especially when dealing with WalMart. My nephew's girlfriend bought him a PSP for Christmas. When they opened it it wouldn't work so they took it back. They refused to exchange it or give them their money back. Herein lies the problem. The serial number on the box and receipt do not match the player in the box. Either Sony mixed things up at packaging, someone at WalMart mixed or switched it or someone had previously exchanged it and switched players. The return dept. is suppose to check this when something is returned and evidently they didn't do their job. Marie watched them pull the box from the glass case and even bought an extended warranty for it. Calls to the store meet with hang ups, lies, and accusations of them doing the switching. Well you can't switch what you don't have. Calls and emails to corporate seemed like it was going to help but so far no luck. Manager at the store claims they back him up. Lady at corporate says to call her again if no success. It's just a run-a-round. We were telling a person who has worked there and he too says they are suppose to check to make sure these things match. He also says there is no reason not to exchange it because WalMart does not lose anything when they do. It goes back to the manufacturer who takes the loss. So they are out a player and their money.
If you purchase a product at WalMart make them open the box and check that serial numbers match before you purchase it. The inconvenience should drive them crazy, lol. We are continuing the calls, spreading the word and my sister Rhonda is putting it in the public forum.
