Samsung — Air conditioner 1.5 ton indoor unit unusual sound

Address: Buxa Hill Forest, Bakshaduar, Post Office Rajabhatkuwa,District Alipurduar,West Bengal

We recently bought a 1.5-ton Samsung air conditioner from Kanchanjanga Refrigeration in Alipurduar city, West Bengal. After installing it in our home at Santalabari Bast, Buxa Hill Forest, we noticed that the indoor unit was making loud noises when releasing cold air. We contacted Samsung India's helpline four times, and each time we were assured that a technician would visit. However, the first technician refused to come because he was located far away in Cooch Bihar. The second technician, from Birpara, was also too far from our location. The third technician, also from Cooch Bihar, didn't show up at all. Finally, the fourth technician arrived but refused to perform any checks or tests, claiming that our location was not covered under his service area. When we reported this to Samsung, they asked us to call the helpline again as they couldn't escalate the issue. It's frustrating to receive such after-sales service from a reputed brand, and we're unsure of what to do next.
