Reliance Digital — issue with body cover of new samsung a20 mobile phone

Hi
This is anuradha naveen, proprietor of anomaa studios, bengaluru. My husband (Naveen) and i have been a loyal customer with reliance for long time and you can verify from your billing/store manager thimme gowda from vijayanagar. Recently i bought a new a20 samsung mobile on 15th july 2019 evening from reliance digital vijayanagar (Attachment 1) to gift to one of my loved ones. Took the phone home with full faith as the person who did the demo mentioned everything is fine. However i found that the back cover is not fixed properly on 16th july when i was about to gift it and immediately informed over the phone to the store manager, that this product has issues. He was prompt in his work and asked me to give it to them so that they will send it to samsung customer care and i handed it over on 17th july (Attachment 2) within 48 hours of taking the phone. I was informed from reliance digital team that vandana communications service centre of samsung is not accepting this phone for replacement/warranty. They are stating that is a cosmetic issue. Isnt it cheating from samsung not to replace the faulty product which was a clear miss from samsung and now asking the customer to use the same faulty phone? Why are you supporting such companies which have least respect for customers. I request you to immediately intervene and arrange to get this replaced. Looking forward for an immediate response and resolution as requested.
Ps: did have a conversation with priya from samsung customer care supervisor desk team along with nagabhushana from reliance team and was communicated that vandana communications service team would share the service tag by 12:50 noon and would revert to us. However, i haven't received any updates till date. I have raised an online complaint no: [protected] for your reference as well.
I request you to immediately intervene and have a word with samsung team to ensure they replace this immediately. Thanks in anticipation
