Samsung - Bio Sleep A. C. Unit — no response after false statement

My complaint no is [protected] registered of 20.5.2009. We were informed that one Kumar will come to attened the complaint. The individual come and collected Rs600/- and informed that the out door unit will be taken and compresser will be replaced. Later on 22.5.2009 one shivakumar came and opened the outdoor unit and said that the outdoor unit will be taken to the company and compressor will be changed. Shivakumar collected Rs713/- and isssued a receipt. Till date no one has come to take the outdoor unit .When enquired on the toll free number about the complaint there was no response and they said that the compressor is not available and it takes time. I am still not convinced and i request you attened to the complaint. The A.C unit was newly installed only last year . I need immediate action .
