Livpure — AMC service not received after due payment

I wanted to get my water purifier servicing done when customer care advised me to renew AMC online which I eventually did. After making the payment it took 2 weeks to get the AMC active (initially they lied I would get the service done within 24 hours of making payment). It's been a month since my AMC was active but they didn't provide me any service or part replacement as per agreed under the AMC terms. The service center they allocated to my residence area, initially denied service as I didn't take AMC directly from them, they termed online AMC activation as a scam. The name of the service center is Livpure - Tanish Enterprises and a lady handles the calls and is very poor in customer service and speaks too rudely. I lodged multiple complaints over calls and emails to the Livpure customer care team but they failed to resolve this and stopped responding back to my emails. I faced loss of money, time, and mental peace. And top of that have no option other than drinking water with purifier issues.
