Motorola Solutions — imei number changed

Address:

620001

I purchased a motorola e4 plus on 09.11.2017. After 2 weeks 4g volte was not supporting hence i was not able to make any calls. I gave the phone to motorola service centre, trichy, tamilnadu on 28.11.2017. They said the mother board had to be replaced and took the phone in their custody. After few days when i called them they said that there is only hardware problem. Finally i got the phone today on 14.12.2017. But when i checked the phone in my residence i found the imei number is entirely different to that of the one i purchased. I don't know how to react to this. Feeling frustrated.
