Sears Installation Defective water heater we have been without water for 3 days Internet Nationwide

Our 7 year old Sears water heater cracked 3 days ago. We were forced to shut off the water to the house because the intake valve was also shot (which Sears had installed when they installed the water heater) and it continued to leak unless we shut off the main valve to the house. We immediately called Sears to have someone come to repair or replace it. No one responded and after several calls the next day, a repair person finally came at 4 pm the next day. After paying him $89.00 he said the water heater was cracked and needed to be replaced. We immediately called Sears to schedule the replacement. They said they were busy and to call back the next morning. We called several times that next morning and were told that a repair person would contact us to schedule the replacement by 2pm. At 2 pm we called and were told that it would take 24-48 hours more to schedule the replacement. When we called Sears again to say this was unacceptable, they said we could go to the store and pick up the water heater ourselves and find out own plumber to install it. This said after we had already paid them almost 400.00 to cover the installation and it is was now 3pm on a Friday afternoon. So now 60+ hours later we have been without water. Sears has been paid for the installation of a new water heater to replace their defective one. We received a call this morning saying they would send a plumber to install the water heater between 1 & 4PM today.  After being put off for three days, we are doubtful this will happen.  We have bought appliances from Sears for over 30 years but will never buy another one from them.
