Pompeii & Amalfi Coast Full-Day Tour from Rome with Lunch

Our guide arrived 45 minutes late, had to stop for gas because he was on empty, then had to stop again for coffee because he was falling asleep on the ride. The tour is described as visiting Pompeii first, then lunch at Positano, then on to a visit to the Almalfi coast. Our guide told us we were going to do the tour in the opposite order: starting in Almalfi, then ending with Pompeii. Because he made this change, in addition to his necessary stops, we arrived at Pompeii and it was closed. He then told his supervisor that it was because of US that we missed Pompeii. What?! We were extremely disappointed. We were promised an English speaking guide, and spent the day with someone we could not understand at all. WE pointed out Vesuvius, to which he told us we were wrong. We then asked what a particular tree was as we were driving and he told us it was a peanut tree. Really? Another stop on the way home for more coffee. A very long, disappointing day, which should have been memorable.
