Purchase from linearmotionbearings2008 is turning out to be a total disaster

[Darko]

Hi everybody,
I am new in building diy cnc and was trying to build my first cnc with about 1000mmx1600 work area.
To make long story short I purchased kit from linearmotionbearings2008 on eBay with all rails and ball nuts. The order arrived two days ago and as soon as I have seen the box that my stuff was shipped in, my heart sank and I thought I’m going to have a hart attack. 1600mm ball screws and 1700mm rails were shipped in the cardboard box with no support of any kind. I knew before opening the box that there is no way that this stuff is not bent. At minimum I assumed that this would be strapped on the flat wooden board if not in the wooden box.
Rails were ok.

You can see ball screws here

I have exchanged few emails with the seller and initiated return on eBay, he didn’t seem to care, offered me 50$ on 750$ order.
Is there anything I can do? Will going to eBay resolution solve anything, what about calling my credit card company?
If this is how this stuff is shipped how does he maintain 100% positive review on eBay. I can’t imagine this happened only to me.

I apologize for my broken English, I’m a foreigner living in US.
Any suggestions
