its2weeks waiting for our stoveto be replace/fixed

We bought a whirlpool stove on the 08/02/15,then on the 07/06/15 while I was cooking the stove just went dead the power was on its just was not becoming hot, we called the electrician who came Monday morning checked his connections and said all was well and since the stove was new he cant open it due to warranty policies .My husband took the stove back to them and was told they will contact Whirlpool to send their technician that was on Sunday 14/06/15.The technician came on the 17/06/15 and told us that one part needs to be replaced he will order and comeback to install it . today marks full weeks waiting, and on Sunday we contacted Dion and told them that we are still waiting Gift promised to call us on Monday he never did then on Wednesday My husband went back to Dion he was promised that by Friday all will be sorted but we are still without a stove, had to buy a two plate to keep us going which was and its still is an inconvenience. We are so frustrated and disappointed.
