Amazon India — Warranty Claim Issue

I had purchased a RAM stick which is a
16GB DDR4 3200MHz SODIMM PC4-25600 CL22 2Rx8 1.2V 260-Pin SO-DIMM Laptop Notebook RAM Memory Module M471A2K43DB1-CWE

It has failed and stopped working. Samsung RAM has 3 years warranty and your Product page claims LIFE TIME WARRANTY as well. I already contacted the Manufacturer Samsung and they have asked me to get back to Amazon who in turn asked me to get a Service Denial Letter . I got the SERVICE DENIAL LETTER but amazon keeps delaying the issue with reasons like your photo was not clear and so on. I have called every 2 days for the past 3 weeks to no avail.
