Lousy Customer Service

On 6/1/09 I sent an order in for a nightshirt & a pair of slippers. They were each $19.99 plus S&H. I got 2 pair of slippers. I followed the instructions exactly for an exchange. I got a check for $13.56. I returned the check with a letter saying I did not want a check for $13.56 & if they didn't have the color nightshirt I wanted I would take any color. I have called, written & e-mailed. It is now 8/8/09 & all I have gotten from my 6/1/09 order is a pair of slippers. I can't see how they can promote themselves as a company who prides themselves on customer service because it's non-existent.
