I will start describing below the horrible experience i had and the extreme lack of attention by the tourism agency. The tour was one month ago and till know, they didn't take any action to know how i was feeling, didnt return my calls, and didnt return part of my money.
1st day, the driver didn't know much about the road and got lost few times on the way fort to wahiba desert, after that, he decided by himself at 3pm that was late to go to Wadi Bani, we stayed in a gas station waiting for someone that never show. He was very impolite when we asked why we were there.
At 4pm, we went to the desert, he started to search our desert camp, the night came and he was very desperate, he was driving more than 100km/h, put me in danger and almost crash the car with other on the opposite side, we spent more than 4 hours at the desert looking for the camp, we asked him many times to take us to a safer place, by the end, he was very rude and told us to sleep in a hotel from his friend that was outside the city, we asked for him to stop and left the car to search for a new hotel, he followed us.
I tried to contact the travel angency by the number they gave me, asked for help, explained the situation, asked for another driver, the person told me to contact a maneger and he not picked up the phone, and the only person who i called on the first place, never picked the phone again.
2nd day, we tried to get a taxi to return to muscat but we couldn't find one, the driver was there in the morning saying that he could drive us back, in the way back he stopped in 2 wadis and didn't do the script planned for the second day, beach, white sands and so on, and haven't provided any information about anything we saw on the trip (and rarely bought water for us)
At the airport we told him that we would not pay the 50% remaining, because we didn't visit places that were planned, didn't sleep at desert campus, spent money to sleep in other hotel and he put my life in danger.
He THREATENED us, saying that we would never leave Oman, would scream and so on. So we payed the money and he left us.
