King Linen Worst purchase ever Internet

I purchased 2 sets of sheets. One flannel and one supposedly 450 thread count.  The flannel sheets were rough.  They shrunk when they were washed.  Then the bottom sheet corners split apart.  The "450 tc" were not like any 450 tc I had ever seen.  They were thin and some of the seams came apart.  They were supposed to be 100% cotton but they pilled and attracted lint. I could not sleep on the pillow cases because of this. Also when they were washed the top sheet shrank to a twin size.
The company said since it was longer than 30 days they could not do anything but then in the same e mail said I should take pictures of the sheets. 
I looked on Bizrate, another ratings site,  and it was apparent that the company employs someone to write fake glowing reports.
