I ordered a laptop computer from MPsuperstore.com. They sent me a note asking me to call them back, and it turned out they just wanted to get me to buy a different computer. They lied on the phone and said the computer I wanted was in stock but it wasn't. I cancelled the order (I should have checked this website first) and a guy at the retailer told me he'd refund the money immediately (I didn't even know they already had charged me), but I still cannot get to the money in my checking account. The bank says the money is on hold and that only the retailer can remove the hold. I've contacted the retailer and the bank numerous times and keep getting the run around.
What can I do??? Because right now there is nothing stopping this retailer from taking $2000 from me. Not to mention I can't get the computer from a more reputable dealer while waiting and hoping that this gets resolved.
