Godrej Locking Solutions & Systems — Got detective lock and couldnt file a warranty

Respected company,
I have purchased all Godrej locks for my new house on June 2 2022 with my previous good experience from the company. Purchased locks from Amazon was a huge mistake. One of the lock body got findout diffective only after the return period. I contacted Godrej customer service they assured a service person in 24 hour. Today it's 15 th day no one appeared. Contacted Amazon, by suggestions given complaint through mail. Still no response. Finally a lock with one year warranty but don't know how to ask forit. Pathetic customer relations. Didn't expect this from reputed Godrej, as we never thought another lock company in our life. That much trust we had in Godrej. My new house got a door with vacant key position embarrassing. Kindly go through it
