I received a scammer call today only an hour after creating my last post on this website! It was someone stating they were from 'Quickbooks Support'. They read my post back to me and after doing some diagnostics and saying my data file extensions were corrupt and needed repaired, offered to repair the problem for $700 to $1600 dollars (see screen shot). 

It's obvious there are people watching this website carefully and scamming people after they make posts! BEWARE!
