Harman India — Product sent for repair was vanished

Ref:Harman - Defective Product Pickup – RMA No:KL-C[protected]
I had sent my Blutooth speaker for repair as per directions from the Harman india customer care .The product was picked up on 5/12/2020 and was delivered to the service partner 'Flextronics' on 10/12/2020.
Today, it's 29/12/2020 .I haven't received any call or email from Harman team and when I asked the customer care regarding this they told me 'Its under repair.'
But as per the policy the customer needs to be informed about the repair and replacement and would get a payment link for the service cost before repair...But nobody contacted me till now and I want to escalate this issue to Consumer court and JBL ..
After raising a complaint one superviser who introduced herself Ms Poonam called me and offered a solution within 48 hours..Now it is over and no response from her side..I lost my product and no information regarding my product..I will file a case for cheating and snatching property through illegitimate means in the court.
