MAKRO SELLS BUT NO SUPPORT

We purchased an AEG stove from Makro. Just prior to extended warranty lapsing, we had to have selector button of stove fixed. a Year later it broke again and for the past 7 months nobody has been able to help us fix the stove (a four year old stove can not be fixed by either Makro or AEG) Pathetic service from both of them and no answers to my problem. How are one to prepare food under these sircumstances.
