Voltas Beko — Dishwasher issue 15 NOV 2023, Not resolved yet

Dear Madam/Sir, I have purchased a VoltasBeko Dishwasher in 2020 for INR 44000/- in Vijayawada through SRR E CITY, D.NO[protected], SAI SIVAPURI COMPLEX, MUSIUM ROAD, VIJAYAWADA 520002.
I got issue with dishwasher on 15 Nov 2023 and lodged a service request (ticket id: [protected]) with VoltasBeko customer service. They approached me after 5days, charged me INR 600/- although the issue is not resolved. They simply closed the ticket. I keep on contact the local Voltas ASM via voice call as well as whatsapp. They came couple of times and just going without resolving the issue. Voltas promised me to provide customer service at the time of purchase. Now, VoltasBeko do not want to support although issue occurred 40 days ago and they are not responding.

Please help me so that VoltasBeko will support. Please note the product age is 2.5years from the date of purchase. I have attached the bill copy for your reference.
