Business ProfileforDefense Tax Group Inc

I called to complain and ask for my money back I have never been berated over the phone by business like this before. They told me I would not get my $500 back. he said I needed to read my agreement that I signed and that I probably couldnt read it because I only have an IQ of 40 and that Im not smart enough to read and I should have my friends read it for me. He found out my profession and insulted me professionally insinuating that I am not capable of doing my job and that I take advantage of people. He called me 11 years old and stated that ** only calling him to impress a female in my vehicle. I was shocked that he would go on a rant so long and still consider himself a professional representing defense tax partners. I strongly dont recommend this company after my interaction with them. Since that phone call, I have received four emails from them warning me that I dont want to take further action because they know attorneys and this would be very costly to me. Then they quoted to real estate law/regulations at me, threatening me with the department of real estate in ******* that they would take action against me. I never had them as a client of mine or represented them in real estate in any fashion. I called for their help for my deceased Fathers estate and I felt taken advantage of, called for restitution and then they became very angry. They made many threats to shut me up from complaints or negative reviews. To be honest, I am scared to leave this review because now Im afraid there are going to try to do something to *** me or to take me to the department of real estate. However I know I didnt do anything wrong so I should be fine and I dont want further headache, but being threatened like this I feel I have to warn the public.
