My wife and I booked 3 flights from Tunis to Tozeur, then they moved the flight times more than 3 hours later into the evening which meant we would have arrived in Tozeur after midnight which was unacceptable to us as we would have my elderly mother-in-law with us. After talking to a Tunisair customer service agent in London we cancelled and requested a refund through the email address we was given by the agent, this was 3 months ago and still have had no reply. Also on the same trip we booked a Tunisair flight from Tunis to Malta so we could spend our last 3 nights there and they changed the flight dates to the next day reducing our trip to 2 nights. In the 30 years I have been travelling I have never experienced such poor customer service and lack of respect for there customers.
