Debra in my experience phone calls and e-mails get you no where. I've always found a good old fashioned face to face slanging match in the middle of the shop in front of other customers usually gets you what you want! No swearing mind as you'll find yourself in steel bracelets quick sharp
Basically, take it to where you bought it from and tell them you want a replacement. By law they have to offer you a repair, replacement or refund, and will usualy do so in that order and since you`re getting no-where with repairs, get a replacement or refund.
