BG Super Tax Accounting

Worst customer service possible. Received a call from a lady at BG Super Tax on 11 of December, saying that I owed money to them for my tax return they did in 2017, when I didn’t do my tax returns until later this year for both 2017 and 2018 and that too I didn’t do it with them. When I started explaining she cuts me off and starts talking in a high pitch telling me to listen to hear first. Definitely wouldn’t recommend them knowing that I’ve been trying to resolve this issue since early last year but no one makes any notes as to what I said.
