Defective merchandise

I sent e�mails to George, Anita, Christina, and Brian on the following dates: 03/31/2008, 04/10/2008, 04/18/2008, 5/12/08, 06/05/2008, 7/2/08, 07/14/2008, 8/12/08. George promised me a complete refund back in January of 2008 when I placed my big order. For three months, I was unable to return their defective merchandise because they would not give me a return voucher. Finally, the three defective plumbing fixtures were returned to the company by UPS about 04/13/08. After calling them several times, in August, 2008, I received a refund credit of $982.21 minus a 15% ($157) restocking fee that they had no right to charge me because they sold me defective merchandise. They kept my $982.21 for over six months. I was never able to get the remaining 15% of the money the company owed me
