I ordered a dual zone heated mattress pad and was sent a less expensive single zone version. I had to take my complaint to PayPal to even receive a response to my inquiry and their only response was that I would need to return the item at my expense and pay a restocking fee of 15%. When the mistake is their fault, I fail to see how I need to come out of pocket twice to fix it. I'll be contacting my credit card company for a better solution and will never purchase from them again.
