I wasn't exactly buying something, but I paid to rent a moving truck (a Budget/Uhaul type place) to move across the country and got them to give us our money back, pay for hotels and $100 worth of food each day for a week, drive the truck for us, and move us in when we got there.
We had nothing but problems from the moment we went to pick it up, the ramp was bolted in which no one knew (wasn't supposed to be that way) so we couldn't load up, waited about 5 hours for a roadside mechanic to come so instead of leaving that night we had to wait until the next morning. Then, one of the chains on the trailer were so rusted that they crumbled when we got the car loaded. Waited another 3 hours for a roadside mechanic to come fix it. Left that afternoon but less than an hour down the road the engine light comes on and the truck won't accelerate past 35 MPH. Pull off, wait another 2 hours for a roadside mechanic to show up. They can't fix it so they put us in a hotel for the night. The next morning, he says he found the problem, the battery just wasn't hooked up all of the way. He fixes it, we head down the road, check engine light comes on and the truck won't accelerate past 35 MPH again. I call furious that it's taken us 2 days to get out of the damn state. They say there's nothing they can do and they will call a mechanic. I say no and demand a supervisor who, after I bitched at him for 30 minutes finally told us to go to another rental place where a truck would be waiting and he would arrange a moving crew to unload our truck into the new one.
We get to the truck rental place and they have no idea who we are or what is going on. They also don't have a truck available in the size we need (which was the biggest they have) and they're in this shady abandoned lot with a crazy amount of dust blowing everywhere from construction across the street.
I call back and he says they don't have a moving crew available for another few hours so "sit tight", but if it makes us feel better they are going to retire that truck because it's unreliable or something. We have small children, 2 cats and a fish sitting in a minivan all day long, so I'm fed up, everyone is miserable and exhausted, and the fish ended up dying a few hours after this phone call.
I demand he hire a driver to drive the truck down there so we can just leave in the van instead of sitting in the car all day long. He says they don't have drivers so there's nothing he can do. I demand to speak to his supervisor and end up going up the chain until I'm talking with someone at their corporate office. I start in on my spiel about how they're going to make my wife lose her job because they expect her there in 2 days and we can't seem to get out of the damn state we are in when she says "just tell me what you want, anything, we will make it happen". I was shocked because I'd been met with nothing but resistance at my, now that I look back on it, a little outrageous demands, but I said I want you to hire a driver, drive the truck down to our new house, pay for hotel and food for us until the truck arrives at our house (because we would already be there by now if it weren't for the problems), hire movers to move us in, and refund us the money for the truck. She agreed and it worked out great. Except as we were leaving the hitch of the trailer the car was on broke and the moving guys couldn't get the car down, not sure how that was fixed, and then when the driver got to our house he locked the keys in the cab, parked on the wrong side of the road and got a ticket, asked for me to give him a ride to the airport which I declined and called a cab for him, and left the gas tank damn near on E.
