Venue 7 Support Numbers

Greetings:

Is there a US support number that I can call and reach a US person, not the PI?

Reason for asking is:

In December I purchased a Venue 7 tablet as a Christmas gift for my son, using my reward points from Marriott.  As luck would have it, he dropped his backpack containing the tablet and now the digitizer no longer works.  I call for service and gave them the Service Tag number.  They are telling me that someone else is the owner of the device according to their records.  The item came in New-In-Box so there cannot be a previous owner.  But all they know (obviously from their script) is that their records must be updated and that the burden is on me to make the transfer.  Transfer on a new in box device?

They are refusing to service my son's tablet because of where/how it was purchased?  I feel like they are implying that I stole the device.

All I want is to get it fixed.

Can someone here help me out?

Regards,

JP
