Hi

It is very easy and simple.
I also had the same problem.

You just go to the Inspection area once again by tomorrow and there will be a Policeman in charge for this kind of issues . Next office of the Inspection office.
You can meet him and explain to him.
He will check your car and put sign/ stamp seal on your
paper .
Thats all. Finish

Then you go to Mamoura Office and get the renewal there.

All the BEST !!!
