Exam center complaint! Software issues help! Please respond immediately!

Today i have sat my Audit and assurance exam for the March 2022 session (7th March). I have faced technical issues on the computer and in my screen there was a medium sized floating window called ‘Input is error’ which kept appearing from the moment I selected my name and started the exam till the end of the exam. I have reported this issue with the invigilators and they did everything they can to solve this problem from changing the system, replacing the monitor to troubleshooting the issues everything they did but nothing has solved the issue. In the meantime, the invigilator was making calls with the Pearson exam delivery software people about this issue and they said it is from your end but after some time the invigilators concluded and said that this is an software issue from their side that they cannot do anything about this and asked me to adjust with this issue and told me that they will let me know if they found a solution about it. They asked me to continue the exam and not waste anymore time, when infact, I already lost upto 20 minutes of time while they were trying to resolve this issue with my system. I continued writing the exam despite the issue being unresolved. The floating window was moving and making a circle in the screen and it kept hiding my question and the answer I was writing that I have to wait for few more seconds for the floating window to pass so that I can read my question clearly. Waiting for the floating window to move for every few seconds everytime cost me a lot of time in the exam that I lost my focus and become very frustrated. I can’t even properly read the question or the answer I was writing and felt very helpless. Even though with this issue still unresolved, i tried so hard to attempt and complete all the questions on time and when i came to the last 20 mark substantive procedures questions I was left with only 5 minutes time and could not fully write the answer and the time was up.
After the exam, I told the invigilators that I could not complete my exam appropriately and on time because of the serious issues that I faced and asked them what action will they undertake for this issue happened and they informed me that an another student from different room have faced the same issue and the issue was not resolved for him either. They told me that they would report this issue for both of the students to the ACCA but they said they do not know of what actions will they undertake regarding this issue and asked me to personally send an email to acca regarding the same issue that I have faced.
I have prepared for this exam so hard that I definitely knew that I would pass this exam but now after finishing my exam I don’t think I will pass the exam and now all my efforts have been wasted because of the exam center’s fault.

My question is what should I do about this serious issue that I faced in the exam center that affected my performance badly? Should I report this issue in the centre compliant section of myacca? If by doing so what actions will they undertake regarding this issue? I want this issue to be considered when marking my exam and I want them to provide grace marks for all the time that I lost in while facing this issue. Please suggest me what should I do?
