I have an extended warranty, but don't have the paperwork, now do I access that information. I tried calling the store and they are not accepting calls.

If you have an Best Buy online account, your warranty is listed on there or you can call their 800 number.

Warranty information is usually associated with your phone number

if you go into any best buy a associate should be able to pull your warranty up by your phone number.

Might have to stop in, they are open

It's best to set an appointment online with geek squad, you may get lucky by walking in. If you have best buy rewards your warranty info will also be your acct. you log into
