[Resolved]  Samsung — Refrigerator Cooling Issue unprofessional Service

I have RT28K3343R2/HL Samsung Refrigerator purchased in the year 2016. on Jun 15th we ran into cooling issue for the lower compartment and forming of ice on the upper door (Freezer). On Jun17th opened SR [protected] after several follow-ups with Customer care[protected] they have sent an engineer on 19th June. Unfortunately it was a power shutdown on that and the engineer who visited tried to open the upper board but as it was frozen he didn't try more and straightaway told that it should be either Sensor issue or Fan issue and he ordered sensor and received 500 as advance and informed that an Engineer will come and fix the sensor on Monday 21.06.2021 but as a wonderful service of Samsung no one has come on that day. Hence I have followed up with Customer Care and Service Center (SR Enterprise) whole day and on next day 22.06.2021 one engineer has come and replaced Sensor and told issue is fixed and asked to check the cooling after few hours but there is no change still the issue persisted. Hence I have called the Customer number on the same day 22.06.2021 and made complaint in the SAMSUNG CEO page. On Next day afternoon 23.06.2021 an Engineer has come and his attitude is not professional without mask. He checked for 15min and told to replace Motherboard when I asked him then what is the reason for replacement of Sensor unit. He told we thought first it could be sensor issue after replacing it we found issue is with Motherboard now and the cost of the Motherboard is 2500/- but still they are not sure what is the real issue. When I have complained about the behavior and the service of the Engineer to the service center. The enigneer called me and asked what did i say about him to the service center. I am really confused the service of Samsung. Still now my issue is not fixed.
