Micromax — Mobile handset exchanged

Sir/madam I purchaased a micromax cg666 cdma gsm mobile from snapdeal.com on 26 feb 2015. everything of the handset was ok except some key were malfunctioning from the new condition. so i gave it to burdwan service centre (b.c.road, kalitala, pin-713101, west bengal), on 18th, july, 2015. they delivered me most prob.25th july. when i asked them to check at the time of delivery, there was no charge in battery. after come back to home i found that my handset was exchanged, IMEI NO. was totally different from my original handset. and the set was faulty, i bring the matter to the notice of service centre, they denied, and told that it may be possible to exchange of inner parts with some other but handset is yours. anyhow they told that battery is damaged so we will make arrange to give uou new battery as it is within 1 year warranty( though my original handset’s battery was totally ok & new condition). they make a requisition for battery on 05/08/15 and deliver me on 04/09/15. and also changed my IMEI NO. TO my orginal imei. but after receiving the new battery same problem persist. battery can't hold charge (when switch is off), with in few hours it automatically discharged. and cdma & gsm shows full tower but incoming and outgoing call can't be done through cdma, but when same sim is installed in other handset at same time it properly works. I went to burdwan service centre again on 12/09/15 (Saturday), they (a lady) told that due to link failure your handset can’t be accepted today. I told that madam “ I am a employee of state bank of india, today is our holiday (2nd Saturday) so it is very difficult to me to make time again within a week. “ she replied, ”this is your problem, what can we do for it?” today (15/09/15) I leave office 15minutes early to reach service centre within 5:30p.m. I tried so many times to this no-[protected] to know about the link (internet) condition but most of the time the number was busy, finally a lady received at 5:11 p.m . I asked her madam I am on the way (in bike) from my office to your service centre (15km). would you please accept my handset if 5 to 10 minutes late. She replied very rudely, her behavior was very rough . I did not go service centre because it will be 5:35p.m to 5:40. Very bitter experience with micromax service centre, burdwan. There is also Samsung service centre at burdwan, their behavior is gentle, polite, customer friendly. Please suggest what should I do? If I take a leave from office & same problem occure (link failure) then my problem will not be solved. i have no faith in burdwan service centre. previously i did contact with you ([protected]@micromaxinfo.com) regarding the matter when my handset was exchanged. i was advised from your end to co-operate with service centre. and this is the result of co-operation. should i sent my handset to you? if the handset can be repaired then please repair it otherwise keep it at your end i don't refund any money. i am very disappointed. please advise to which address should i send it? kindly don't advice to give it to burdwan centre, because they don't receive handset after 5:30pm, and deliver within 6:00pm. as i am an employee of state bank of india it is impossible for me to reach at service centre within stipulated time except holiday for this worst quality of service.
