Have proof broker is manipulating charts

Hello,
First of let me start by saying that I am not an upset or angry people because I have lost some equity, I own up to the fact that this is a result of my trading. I believe that if my mistakes mine then I need to own them and move forward, but what if the broker is playing games with you also?!

I had a short position open on AUDJPY at 8:58 GMT+5:30 their bars were changing with the price but the bar was from 8:45 open and did not close at 8:50 (5 min chart). I watched as price dropped below 81.15 that low does not even show up. I just looked again and the candle is still open at 9:25 GMT.+5:30 Had I not watched this position on the charts I would have missed a massive pin bar that sent price up past 81.20.

I have taken several screenshots on my phone. How do I take action against them? I did not lose much on this trade, but who knows how many different times this has happened. I also watched it happen on USDJPY and again lost money there too.

I want to take action against them because this not only has taken money from me but probably countless other people too. Advice welcomed please.

Thank you

Look at my chart below. This is a live D1 EU chart and it does not update bid line and also candles. It only appears on D1, no matter if I open a new one. All else works normal. Seems to be a MT4 bug. Could be a bug of your terminal too.
