Asus India — Sim card slot 2 not working - though repaired twice since purchase at Authorised service centre

Address:

Akola, Maharashtra, 444001

Sir/ madam,

I had purchased an asus zenfone 2 ze55 1 ml from muskan on 06/11/15. Since its purchase i have send my cell phone to authorised service centre saffalya computing, tilak road akola. For the same problem that is the sim card slot 2 stops reading the sim card. Last 2 services were provided free of cost and i was asasured that the problem is solved. But again the problem recurred on 29/10/2016.
I tried to contact the service centre but it is closed due to festive season since 4 days. Today again i tried to contact them but they said that the service centre will open on monday. My cell phone was purchased on 06/11/2015 so it is still under warranty but on monday the warranty will expire. I requested them but they denied the request. Kindly look into the matter and do the needful. I am uploading the photos of bill and phone imei and product details.
