Faced technical glitch during submission of March 8 test

I took my sat exam on March 8 and faced technical issues and early submission problem but it's that ... I didn't know I could report about it. At the time, I did inform the proctor and reported my experience as poor to collegeboard.

It's only yesterday that I saw all these posts realising I wasn't the only one who experienced it and immediately sent them a complain and have also emailed them.

Do you think I'm too late or will they still entertain my complain? I had internet issues in my country due to which I was offline for past days. I also tried calling the international number yesterday but nobody responded.

I'm so confused. Should I be hopeful for a solution or give up trying to contact them?
