Hello, Thank you for your message. Unfortunately, I think you didn't see the product description and inclusions. This tour that you booked doesn't include going to the Rock of Gibraltar.
On the description and inclusion, you can also see that the driver does NOT enter into Gibraltar. They are not allowed to enter. Public transportation is included as you can see in the inclusions of your voucher, but if you anted private transport, that is NOT included.
The guide is with you all day but the driver needs to wait at the border. This is specified and explained in the description of the tour.
Sorry you didn't enjoy the experience.
Let us know if you need anything else.
