What is the best way to get back at a company?

For the past 6 months i have done research on computers, hoping to get a laptop on a big black friday price cut. 6 months, 180 gruelling days of waiting. Then on black friday, a wild deal appears! Tigerdirect has $350 off? No way! I then recieve the wrong package which contains someone elses order. I send it back, and ask for a new shipment. Guess what? The model isnt sold anymore. They offer a pitiful laptop for the price of the good one when it was on sale. I decline, and i request that i get the new model of the good laptop that is the same price as the good one was before it was one sale. Sounds fair, right? WRONG. They say no way. Then te lady doesnt call back. I will call tomorow, but i have a question: how do i get back at Tigerdirect?
