EXPENSIVE ELECTRIC BLANKETS THAT DOES NOT WORK AFTER A WEEK

Hi a week ago I emailed Econo Heat , I bought 2 electric blankets a year ago . One Queen and one double bed size. No service , they don't even email or phone you back. The 2 x electric blankets just warming up on one side of the bed.... Paid a lot of money for this product , because it's washable. Used for a week, and put it back in the box ..... So it will be much appreciated to get a answer on this matter. You can't complain about the service, because there is no service!
