Goodwill

One thing I like to do is update my reviews a lot, try to keep them relevant to a place I go to a lot so that people can get a decent idea of what is going on there.
Well, after the stunning review of Goodwill I put up on Unilocal last month I’ve come back to put it back to where it was in the first place, when I reviewed the very first time on Google’s review area.
After almost a month of Chinese water torture trying to get an item from them, the service I thought I saw has melted into a black puddle and slid down the sidewalk into the gutter.
It started like this, a month ago my full size mattress broke, the springs decided to go kaput, I humbly admit I am not a wealthy person, so I notice that this Goodwill has many mattresses and for a decent price, so I decide to go searching for one. Now, the very first day I was looking or one, I made it clear to a larger set female employee and a thinner male employee that I was looking for a full size mattress. They were very nice about it and said to keep checking back, but that was the only time it was ever nice, easy and clean again.
A comedy of errors proceeded, whether it was from lack of service, cashiers or just plain bad luck I’ve missed over nine mattresses from Goodwill, most of them were due to the employees not telling me truthfully over the telephone whether they had one or not, due to laziness or what, I’m really not sure.
The worst happened about a week ago, they had a very nice looking mattress, and I was excited because my patience was wearing thin, so I ran up the counter behind a couple who was shopping through the jewellery case. Now at a regular store Target, Walmart, etc… The employee would have checked me out or there would have been another cashier, instead she completely ignored me, while the couple for ten minutes picked out jewellery and I fidgeted in line. I even tried to audibly ask for help and point to the mattress. Finally, after those minutes had slowly passed another person finally appeared at the checkout counter with Usain Bolt speed I asked «Please, can I buy that mattress.» and the other cashier turned and rudely looked me up and down and said «These people just bought it.»
Now, I’m pretty calm but I shouted «WHAT?!» at the top of my lungs and proceeded to storm out of the store. I mean, really? If you had attended me when you should have, the mattress I’ve been obviously coming into your store for the last month for would’ve been mine, I had the cash in hand, ready to pay. I’m pretty damned sure that these people notice me coming in and leaving every day. So, another mattress appears, and this one is on hold… FOR THREE DAYS. Now, their policy is, as I have been told to only hold something for one business day. Apparently this is only relevant some of the time.
I politely ask if they could call me if they get a mattress… «No.» and since they won’t inform me when they honestly have one on the phone, what am I supposed to do?
Look, I know it’s Goodwill, right? It’s not supposed to have five star service, but it’s also not supposed to be Dante’s Inferno, either.
