No response for permanent residence

Dears,

Hope you all have a great 2024.

I was checking to get some feedback on my situation. Perhaps it can help me move forward.

As it's more than 7 years continuously, I had applied for PR ( L card) freshly in Schaerbeek commune and received by Bis 16, which also clearly states the ministry has to decide by 5 months. It's more than 8 months now since I received Bis 16.

When we visited the commune thinking that we can ask for PR ( like many forums here suggest) as it's more than 5 months, we have been sent back twice saying we need to wait for a response.

Meanwhile however managing here with a single permit A card which has three year validity. And since it's 3 year tenure expires this coming Aug, I was really hoping to get the PR to avoid having to submit another single permit application.

Now, what do you feel are the best options I have here considering my inputs provided.

And why my commune doesn't provide it to me as it's 8 months since the application. What are my rights here.

Thanks in advance for your inputs.
