Claming of Estimote Proxitimity Beacon

Our HR people bought the estimote Proximity Beacon kit through Amazon(india) Link :https://www.amazon.in/dp/B01M7SREI7/?coliid=I14HT1PJZNTKQK&colid=WTRNR568YL5L&psc=0

i want to develop indoor tracking system using this kit, but when i am claiming the beacon estimote app says email sent to owners email id, and person who has bought these beacon through amazon is not receiving any claiming mails .He has registered on estimote cloud also.

I have read documentation of how to transfer beacon and all but owner is not receiving any mail what should I do?
