Tigerdirect & Onrebate.com ripoff for $90.00 on a Fugi monitor rebate, sent rebate certified but never recieved check Miami Florida

I ordered a monitor from tigerdirect.com which had 2 rebates one a $30.00 & $90.00. I sent both rebates the same day by registered mail and recieved convermation that both rebate forms had been recieved and signed for. I recieved several emails regarding the $30.00 rebate as to it progress and when I should see the check. However I never recieved any information on the $90.00 rebate I call and emailed both tigerdirect.com & Onrebate.com, both said they would look into the issue and get back to me, this happened 3 times. Finally I gave up it has now been over 4 months I recieved the $30.00 check 6 to 8 weeks ago but nothing on the $90.00
