Outstanding Balance, No Explanation Where it Comes From

I have an Edgars account managed by RCS. Very unsatisfactory service from them. I can't even get a monthly statement from them, they just don't send anything even after sending them my e-mail address and giving it to them over the phone. I asked for a detailed long term statement to check the transactions for any ********** activity. They only sent one for September 2020, no other period of the year. There is no way of knowing where the outstanding balance is coming from because of limited to no communication from them.
