Ok guys, looking for feedback here.
Story time.
Back in late June I placed an order with Wayfare.com for 2 items, one of which was a new window air conditioner, with an advertised delivery date of early July. First item delivered as planned but while tracking the shipment it was noted that the AC was backordered to late September. Since we had a lot of summer ahead of us I cancelled the AC order and bought it from ABT, who delivered it next day. I checked my CC on line a couple times to make sure I wasn't billed for the AC, which I wasn't. I thought nothing more about it until last Saturday, Sept 7, when, you guessed it, I found the AC on my front porch.

First thing I did is check my CC on line again but they still didn't bill me. I called them last Wednesday evening, the 9th, to let them know what happened and was told I'd get a call back in 24 to 72 hours to schedule a pick up date. Well, I never heard from them. So I just now tried to call them again and got trapped in voicemail purgatory and got a recording saying their customer service department was closed. Tried twice more to get through and finally got a sales dude. I explained my situ, reminded him that, by law, if I get shipped something I did not ask for, I don't have to pay for it and can keep it, so I was trying to do Wayfare a favor, and, in fact, this was my SECOND attempt to do so. He then told me that since he was just in sales he couldn't help me but he'd transfer me to someone who could. Great, thanks. He then transferred me to the same automated purgatory that I was in a few minutes before.
So, do I try a third time, or do I say fuck it, I've done enough and just keep the stupid thing? Actually, it would technically be a forth attempt because I first tried to email them through their website but it kept giving me an error message so my email never went through. I just checked again now and my CC has still not been billed.
I'm leaning toward calling once more tomorrow a little earlier because when I called last week and got through it was a few minutes before 6:56 pm CST but today I called at 7:06 pm. But seriously, how much of my personal time do I continue to devote to this

?
