Trai — Request for the response on my previous complaint

As I have already mentioned in the previous complaint that I have bought a smartwatch APlus with sim card slot which was detecting mobile networks and was working fine for one or two days and then it was unable to detect the mobile networks although occasionally it worked. As I enquired about it through some friends working in telecom sector, they informed me that the device with the imei no:[protected] is blacklisted. I am requesting to help me resolve the problem by releasing and enabling again my blacklisted or blocked device with imei no :[protected]. Thanking you.
