@The Cookie Monster First; sorry for your loss, many of us here know what it is like to have a complete loss and can empathize with how that feels. I myself am also a Real Estate Photographer and have been using my Plus since July and for a year and a half before that; the standard Typhoon H with a combined 450 flights and zero issues.
Also you should know that this forum has no affiliation with the company that makes these products but is a great place to get help from like minded hobbyists and professionals. In fact you will likely get more help from this forum in regards to Yuneec's products than just about anywhere else.
So to begin, Yuneec will (most likely) not respond in the manner you have asked them to - giving you a call, and I am pretty sure none of the other manufacturers would either. The best way is to contact Yuneec CS as soon as they open Monday thru Friday at 8 AM, Pacific Time. Yuneec has, in the past owned up to their mistakes or defects that cause a lose. There are many pilots here that have had a full replacement when the loss was through no fault of their own. But to be sure, a phone call is almost always the best way to get the ball rolling and an email almost never works with Yuneec CS.
If you would like any help from this forum it would help to give a more detailed description of the events leading up to the crash and perhaps a bit about your time with the H Plus before the crash. How many flights before the crash, battery conditions, and anything else you can tell us.
Also if you will need to access your telemetry files; this will be the first thing Yuneec asks for and if you like you can post the files from your last flight here and someone from this forum can look into them and perhaps gain some insight as to what happened.
Here is a link to show you how to get the telemetry files.
