My awful experience at Sam's Club today!!! (kinda long)

So I go to Sam's to purchase an artificial Christmas tree................I'm in my car and while I had my doubts as to whether it would fit in the back seat, I crossed my fingers. So I purchase the tree and get to door and ask if there was anyone that could help me load the box, "Sure" was the answer and I hear them call over the intercom for help..........ten minutes later there's no sign of anyone so I ask again.........five minutes later, I ask again.......finally two guys show up and we head out to my car which is on the far side of the parking lot (because the place was so packed). As we are walking out I tell the guy that I doubt the tree will fit in my back seat so we might have to put it in the trunk and tie my trunk down. His reply was, "we can't do that because if the tree were to fall out, we would be libel". Hmmmm, okay........I'll buy that. By this time we've reached my car and sure enough, it won't go in the back seat so I head to the trunk and I say to him, "I know you can't tie it down but would you stand there and tell ME how to tie it down?" He reluctantly says, "Okay, do you have any twine?" "No, I don't have twine, I thought the store had twine for situations like this." "Yes, it's up there in a box by the entrance" and with that he folded his arms and leaned back against my car. Sooooooooooo, by now, I'm getting a little upset but I head back up to the box where the twine is supposed to be kept and guess what....................no twine. I ask another employee standing there if they have any twine and he says, "Let me check" and he gets on the radio and I hear the person responding say "Let me go to receiving". So I tell the guy, I'm going back to get my car and pull it up here while you try to locate the twine. I go back across the parking lot and the first guy is still standing there with his arms crossed leaning up against my car. I tell him about the twine and he says he will meet me at the entrance.. I pull my car up to the loading zone and now both guys are standing there. I hear someone page the second guy and say, "We are out of twine, we'll have to order some." Then he looks at me and says, "I'm sorry M'am". So I said okay, well, then  you can put it back on the cart and take it back inside and I'll return it. I get back inside to customer service and naturally the sweet young girl asks me why I'm returning the tree and I proceed to tell her.........I was nice....and she said, "Let me call a manager, surely there is something we can do." So, she calls a manager and I wait another then minutes until this lady shows up and I tell her the whole story. She gets on her radio and thinks she can work magic so I wait another ten minutes and still now twine. Finally, she comes up and she says, "Do you think zip ties will work?" Now, when I think of zip ties, I think of them as at least a foot long so I respond.............."well, they might work." So she goes to get them and returns with a handful of four inch zip ties................I just shook my head and said............."Just refund my money...........I want to go home..............." They did and I did, with no tree. They lost a $200 sale because they didn't a $5 ball of twine................
