[Resolved]  Samsung Microwave M1630n — parts not available

I have bought microwave Samsung M1630N has got its front panel not working. The touch pad needs to be replaced tells the Costumer care personnel.
its been around 6 months that the part has not been received. Complete mismanagement. It is so inspite of daily reminders over phone.
what should be done??
Frustrated with the company i have already done a lot of negative advertising about its products and pledged not to buy another Samsung Product.

kindly tell how can i get my equipment fixed.
