[Resolved]  Samsung — Window A/C installing

I had purchased samsung Window A/C in April 2008 in M/S Rasi & Co Porur chennai-116 Tamil nadu. When I purchase the A/C i got the service engineeer number from one of the person in shop and i called the particluer person also he told to me the shop person does not informed about your purchase and i gave the details of my address. When I called him he said "I will come today evening" daily and finalyy he informed to charge 250 /- for installing and i also agreed for that becasue i need result.But up to date there is no person come for installing. these are people good in only selling the product and never mind the customer services and and do they know how to work? I don't understand why a prestigious organisation like Samsung are blind towards such service providers in the country. Are they interested in only selling their product promising services by mouth and never look into it in future?
