Returned a bad dvr on nov 12 per their instructions. Took to fed x shipping center and got reference number and proof they sent it. Today i got a letter stating they will charge me in about a week if they dont get it. Called got reps who were of no help. Constantly put on hold. Told they would enter the reference number but i might still be charged. my plan is to dispute the charge on my credit card..any other ideas are appreciated. Sent a message also via facebook. Sometimes this seems to work.
