Jenn-Air ripoff - Range turns it self on to boil High 7 home calls Cleveland Tennessee

i have a jenn-air range model jgs8750ads,seril 12802744cg. purchase 7/03 to this date i had 7 house calls. the oven turns it self on to boil high, good thing i was home at the time. new parts were replace but it keeps happening again and again. i have another service call for 8/24now it's reading cook time. none of the buttons work on the board. i can not bake or boil. this range sucks. for the price i paid for this $2,000.00 i should have something that works right.
