Damaged coffee table glass because of the stores negligence

My partner and I went to decofurn to buy a coffee shop and a TV stand the service we received was very poor the items that we bought required that we install them ourselves we paid for the items then went to the warehouse to collect them the person that was assisting us showed us the coffee table being a customer that didn't know how it must be packed and how the glasses were supposed to be protected from colliding with each other as soon as we got home when trying to offload we heard a vibration we immediately went back to the store to tell them what happened we spoke to a lady by name of maryln the way she was sooooo rude telling us whatever happens after the inspection has nothing to do with them we requested that they guys that were Assisting with wrapping and loading the coffee table to tell us how the glass broke when the guys opened a sealed box with the same coffee table we noticed that the packaging is not the same how the glasses were wrapped and protected from each other was not the same as ours the guy was asked what happened with our box he admitted that he took off the plastics during inspection and didn't put then back because they couldn't sit properly we were then told to send an email and attach the pictures that was on Thursday they said we must wait for feedback on Friday, we didn't get any communication this morning which is Monday my partner gets a call to inform us that there is nothing they can do since we are the ones that confirmed that the coffee table was fine...I am so disappointed with the decofurn store
