Amazon India — Amazon Firestick 2nd Gen

All the Amazon firestick 2nd Generation has stopped working since Friday 19th Aug 2022. I've contacted support team they said it's a global issue and will be fixed within 48 hours. But, no solution was provided. Again after 48 hours I contacted and they said will be fixed soon. But, now they're not giving any timeline also I've asked for replacing it with higher version which is working. They denied to provide also they are not resolving the error. Why would people buy Firestick if such interruption and pathetic service.
