Hi Hadi,
This is such a devastating experience that you had to go through. The online Pearson exam is very tough on making sure people are not cheating. They try to do their best to make sure the integrity of the exam is preserved, and it is tough to do when the only means they have is a laptop camera without 360 view. Having said that, I agree the experience is not a pleasant one. During my online exam, they constantly interrupted by asking me not to keep my hands close to the mouth, or not talking/mumbling questions/answers, etc. Honestly, I was afraid to even look up above the screen or even look at the window. The experience was very stressful, and I was determined that if I don't pass, I won't be retaking an online exam.
In your situation, can you consider taking an exam in offline exam centers? I wouldn't suggest trying the online exam again - the experience won't likely change. But also, please engage with Pearson/PMI to try to get the results of their investigation of your exam experience.
Please keep your head high and be assured that you have done nothing wrong.
