Samsung Microwave - Ce 297dl — not attending properly my complaint

Address:

Lucknow, Uttar Pradesh

I purchased the said model in 2007. Recently there was a problem with the appliance, for which lodged a complaint (Complaint No.: [protected]) in their (samsung) toll free number. But to my utter surprise, the company personel came after 4 days and in a very clumsy manner said the damaged part will be available after 20-25 days. Now tell me i am a man of well above 60 years, both me & my wife depend on microwave for cooking & if we get such an irresponsible response response - then what to do?
