Managing committee not responding

Dear Sir/Madam, I have given a complaint to the managing committee about one flat owner parking his extra car next to my garage in the open space and this is causing problems to me since his cars trunk is obstructing the drive way to my garage from the left side and also it gets difficult whilst reversing as well. He is not ready to move and even the managing committee is not doing anything about it. All they are saying is that subcommittee is formed and they will submit a report . The problem is the owner of the car is in the subcommittee and the other members in the subcommittee are his friends as well and thats the reason its been more than 10 months the report is not submitted. The MC have given the subcommittee time till 14.09.2020 to submit a report on finding a suitable space for these extra cars (who are paying rent rupees 450 a month to the society )so that they don't obstruct any other car. What to do after the 14th of September if the report is not submitted and what should i tell the MC after the 14th of September. Also one of the member in the subcommittee is a defaulter as well. Can a defaulter attend the AGM and also be appointed to be a part of the subcommittee. Thanking you in advance.
