Hi To file a claim it looks like you need to send an email with the details using their contact form here:
Support Android Tablets at an Economical Value Ematic Below is a link to their Shipping and Warranty Policy, although your extended warranty may alter these depending upon what is covered.
Shipping Policy Warranty It also mentioned a tel number - 1-888-968-1985 - which I presume is the one you tried, but worth trying if not.I don\'t where you are situated but in the UK, the contract for a sale is between Purchaser and Vendor, it may be the same where you are so it may be worth going back to where you bought it (unless of course you bought it direct !!) as they may be able to help with more and different contact numbers. Also if they sold you the extended warranty, that warranty may be with an insurance company rather than the manufacturer, so you would need to contact them.Hope this is helpful, if so would you please register that with Fixya Cheers
