Instant Tax Service Michelle Moya was my tax preparer for two years and last year my refund was suppose to be $6,729 instead I only recieved $5,974.05. Antioch California

I went to Instant Tax Services located on 1848 A Street, Antioch, CA 94509 inside of the Western Union building.  Michelle Moya was my tax preparer. Last year she said my refund amount would be $6729.00 when I actually went to pick up my check it was for $5,974.05.  She didn't give me an answer when I asked her where did the $754.95 went.  She never told me how much she charges for doing my taxes.  As read in a privious report this is not Michelle first time ripping poor people off of their hard earn money.
