Debt settled, record clear, but facing lifetime ban in Dubai. What to do?

Dear Sir/Madam,

My debt was settled with the bankers in 2017. My colleague was checking in at a police station in Dubai and my record is clear; that being said, there is no ban.

However, another PRO has said that I have a lifetime ban and must pay a sum of 40,000 Dhs to lift the ban.

Can you please clarify whether I need to clear this from the immigration system or if both the police and immigration systems are the same?
