late delivery/tank not full

After booking in August for a Chrystler Voyager to be picked up in Cape Town on 23rd December 2015, we where disappointed that the vehicle was not ready. The morning on the 23Rd the Manager , Shafiek call ed me to ask if we don't want to upgrade to a Jeep. I told him that we booked a Voyager (a seven seater) because we are six people and the the Jeep was a five seater. He assured me that the vehicle will be ready. On arrival that evening at 8.15 pm we were told that there is only a Jeep available. This after making a booking 5 month earlier. After a two hour insistence we were told that a voyager is available in the stock holding area some 20 min away. After a further delay<br> We eventually got our vehicle. When we were close our hotel on the highway u realised that our tank was not full completely.
