Carrier Airconditioning & Refrigeration / Carrierindia.com — Carrier cyclojet split ac

I have bought this carrier AC cyclojet split AC 3 years back. I bought AMC also last year as during visit the technician suggested to buy the AMC since the service will be free and fast. But to my dismay this year when the temperature has become unbearable I tried using the AC but it didnt work. Upon raising complaint they checked and confirmed the compressor is not working and would replace that. But till date its been 3 weeks no one has been of any help till now. Neither their customer executive are responding. I hope carrier customer service keeps up the brand name and provide me solution as fast as possible.
