Anyone else had problems with Rebateshq.com?

[aphex]

I finally had enough. After my 3rd rebate from them was falsely invalidated, i called em up and bitched em out. After 20 mins of yelling, I now have $115 in checks that will arrive in 4-6 weeks. Has anyone else had problems with them invalidating rebates for no reason? One of them they even had the gall to say was submitted after the postmark by date. I thought that was funny considering i bought the product the 2nd day of the sale and mailed the rebate the SAME day. According to their records, they recieved it almost 2 months later. MMMhmmmm, sure... Anyone else?
