Following up on my last post. Got great help in a private message conversation with the Dell Customer Care team. Issue now solved. Kudos to the Customer Care person who solved my problem!!
Bought a new laptop in May 2020 along with 3 years premium support.  After a number of months the camera failed and Dell issued a replacement machine.  HOWEVER they have not transferred my support package or provided warranty on the replacement machine.  Despite chasing for several months the only support I now have is via phone call which is charged at a premium rate. Email and chat have been disabled and the original SR closed .  Did try the support number and told they could not help me. Is this policy? How can I get my warranty and Premium support back? 
Faulty laptop replaced, warranty and premium support not transferred
