Poor handling

I submitted a complaint almost 2 weeks ago with the NFOSA and have been trying to get hold of them to confirm whether my matter has been received or not but my attempts are in vain. I called multiple times requesting that the agent that assisted me call me back or respond via email for confirmation of receipt and I was asked to leave my number and he would call back but nothing til this minute, I sent him an email on his address that he had provided me with but he has not responded. They are giving me absolutely no hope regarding the matter I have escalated to them when things are already starting on the wrong foot, they are proving to be unreliable.
