Car selling fraud

I had a deal with a transport company to buy a vehicle. I had given them post-dated cheques to hand over the vehicle to me. After that, neither they handed over the vehicle nor returned the cheques.

I tried to contact them but all in vain. In the end, I had registered a case in Dubai Courts. The case was referred to AMICABLE Disputes Department. No one from that company came for the hearing.

A guy in AMICABLE Department told me that they tried to contact the company on contact details e.g. mobile number, landline and fax & physical address provided on their trade license but could not have a contact.

So I was told that the case will be referred back to Dubai Courts and I need to get a hearing date from the Judge. Yesterday I approached the bank and asked them if I can block the issued cheques and I was told that yes, it can be done.

My question is that, will it be a wise step to block the cheques and continue the case in court?

Kindly suggest.

Thank You.

Regards.
