Unprofessional Support

I contacted support about a platform issue. They told me that it's my fault and that I should expect platform issues(I shouldn't expect the platform to work? lol. Then why is this platform even used for evaluations). After back and forth through multiple emails, it was obvious they weren't really reading the emails on my initial request. Then when I told them it was unprofessional to not respond to a previous email and give further information and I'd like either a refund or fix the issue. I was only told "I'm unclear on how it is unprofessional on my part" "Was there something to be gained on my part?". Once again only responding to the part of my email where I called them unprofessional and not responding to the main point, which is I wanted the account fixed or a refund.
