Amazon India — Mobile with Wrong IMEI

Address:	Surat, Gujarat, 395002
Website:	www.amazon.in

Respected sir,
I bought Red mi note 3 mobile from Amazon on Date 27 April 2016 and after 4 month there are exchange offer come on flipkart but before exchange flipkart ask for enter IMEI number. so, i Entered my mobile's IMEI number but flipkart says that INVALID number. so, I go to XIOMI online validator website and i have also enter IMEI number on XIOMI standard website but still XIOMI(Company of Mobile) said invalid IMEI.So, I called to Amazon on date 11-sept-2016, they said you have to contact our Seller CLOUDTAIL . it is amazon's verified seller. so, i have done contact to cloudtail but they didn't gave proper response. I tried a lots of time to contact them but everytime they send different invoice. but According to me different invoice is not a solution because IMEI number is unique number of mobile and we can't change it. and even IMEI number must have on company's database but it said invalid IMEI. And i tried to contact amazon lot's of time but they don't give me proper replay. Please help me regarding this for Replacement of mobile or Refund of Mobile. Because due to fake IMEI i am not able to Exchange on flipkart or even sell on OLX due to fake IMEI number. Now consumer forums only hope for middle class family like me otherwise nobody is here to solve our problem. please help me regarding this. Here i have Attached the Screenshot of INVOICE sent by Cloudtail. And Screen Shot of My IMEI number and XIOMI website indicate that INVALID IMEI.
Waiting for a positive response,
Best Regards,
Badal Shah
