Department of Mechanical Engineering, IIT Guwahati

Almost one month back, I purchsed one Morphy Richards 28 RSS 28 Litre Oven Toaster Griller. However the cake is burning as the heat is not uniformly distributed or there may be some problem in the cotroller. I am looking for a solution. Although I am supposed to return, however the return window has colsed.
Need replacement or repair.
