Poor service

I bought a Serta Pillow from The mattress Warehouse and it took 2 weeks for them to deliver it. I tried returning the pillow because is hard as a rock but they are refusing to take it back because I used it. I used it with a pillow case and a protector for an hour only.

They need to update their website clearly stating if the pillows are soft, medium and hard like a rock. By not supplying sufficient information they are misleading us.
