At&T U-Verse AT&T Corperate OFFICE / Donna Ammon faulty install and equipment damaged m tv, home theather system ,dvd player Internet

My TV, DVD and home theater system was damaged by faulty AT&T U-verse equipment.  I switched my service to AT&T U-verse because the company claimed to have better pricing, cable TV and internet service.  And it has turned out not to be true.  The AT&T U-verse service started in June 06 and since then I have had at least 14 repair technicians at my home due to faulty equipment and poor cable and internet service.  In October 09, a repair technician  was sent out because my service went out again.  The repairtechnician said the AT&T D V R Box was bad and he installed a new one and and tested this box and stated that it had an electric feed back a loud humming noise so he installed a device called an isobar to fix this problem.  On 6/18/10, my service went out again.   A repair technician came to my home on 6/19/10 to fix this problem but he could not get my TV, DVD and home theater system to come back on.  The repair technician  spoke with a U-verse customer repair   technician and reported that he heard a sizzling sound coming from the isobar that was installed in October 09.  The U-verse customer repair technician gave me a property damage claim number.  An hour after the repair technician left, the service went out again.  On 6/20/10,  third day without service,  a technician arrived to fix the problem with the service.  The service went out again and a technician was out on 6/21/10.   Later, an AT&T representative came out to access the damage to my property and took the Isobar device.  Since then, everyday I have contacted AT&T, the  executive office and Sedgwick Claims and they refuse to resolve this matter and have my property fixed or replaced.
