Tiger Direct tigerdirect.com Multiple Agreements to Refund but No Refund Internet

I ordered $4,000 worth of CCTV supplies.  Within 20 minutes of placing the order a change of plans prompted me to cancel the order.  I waited 1:06 on hold to reach a company agent who cancelled my order but who could not reverse the debit  (not credit card - checking acc cash).  The money left my checking account immediately.  However, they gave me a "cancellation number."

Four days later, I called to ask when my $4,000 would be returned.  They responded that it was too late to cancel the order.  After haggling, they realized that though they had the cancellation, they had not cancelled and the shipment went out that day.  Upshot is that I needed to refuse the shipment, then call them back when the merchandise was received back.

So I waited, UPS dropped the 3-large boxes of merchandise without a signature, so then I needed to call UPS to "refuse" the shipment.  5 days later, they picked up the boxes.

Since then, I've called every couple days to check on the status of my refund.  Each time, I am assured that in 2-4 days the money would be put back in my checking.  6 weeks to the day of both ordering and cancelling the order, the money for the merchandise was put back in my checking MINUS $270 for extended warranty which they still owe me.  I've just called to ask about that and was told to wait another 2-4 business days.  I was embarrassed for the poor guy helping me who had no way to help me except to write another email to someone. . . They probably will refund the remaining $270 but to date, I am still ripped off.  Without my constant calling and checking up, none of the money would have been refunded, of this I am sure.  This has been time consuming and unsatisfactory service.  I won't call them again as transaction was too much of a hassle and too much money was as stake.
