Kushan Patel's Review Sourced from Google
Very poor experience, i have been follwoing up for more than 08 months for simple accouting work, which BDO's Sr manager(Adelaide Office) was not able to address. Simply delaying work without a reason. I have asked for refund, which they promised and never paid back. Stay away at all cost.
