You will need longer than 3 days. The lens will have to be ground down to fit a new frame and this is usually done in Jakarta for multifocal.
Why don't you just go back to optometrist you bought them from and change the frame to a different colour? Most will do this if you are not happy.
You will be able to have plain lenses fitted for sunglasses in that time though. Maybe :)
