Momentum student medical aid unfair requests

I am part of a group of students that has app**** for student medical aid with momentum. We all have the exact same registration documentation exact same degree. Our applications are almost identical. I was the only one requested to provide additional documentation and was not given adequate reasoning as to why this is so. I feel that we should all have had the same experience and not be biased for any reason. I am in a position to make these claims as I have sufficient evidence. I do not understand why I am required to provide an affidavit stating that I only have one bank account when provided these details for debit. It has been a terrible experience knowing you are being treated differently for some or other reason
