Filing a case and appointing expert in a bank loan dispute

Dear Mr Ibrahim,

I have a dispute with my mortgage bank.

They have been overcharging me, I am sure of it. It is Islamic finance and after 11 years of paying a total of AED 1.2M, my principal has only reduced by 100,000 dirhams.

I have asked them for all my statements and calculations but they do not respond. I am applying for Canadian PR. I am concerned they will bounce my security cheque to put pressure on me and then I will not get PCC.

Can we approach the court to let them know this is a dispute and remove the bounced cheque from records as I wish to settle with the bank but they do not respond?

Thanks
