Haier India Deep Freezer — Complaint regarding after sales service

I had booked a service online for my Haier Window AC (which is under company AMC till 2025) and i called Haier service number 3 time firstly on 15 April near about 1.35 pm afternoon then 16 April after that 17 April no technician came to visit . So the issue basically was after dialing 3times on Haier services no one visiting and concerning about my problem. The technician made calls and always submit that he is coming or he is on the way but no one visited till now my issue wasn't solved because no one dealing with my problem customer care always mentioned that they are working on it but no one called me and ask about my problem. I was still not satisfied...
