I had a return flight from Brazil to Lethem, Guyana back in September. My connection in Manaus was delayed and so it was obvious that I would not make my flight from Lethem back to Georgetown, which happened to be the last one of the day. The representative from Azul Airlines tried to call the Trans Guyana Airways number printed on the passenger ticket and baggage check but no one ever picked up. She finally wrote a letter which she gave to me to take back. At the hotel I also tried to get through via phone and TGA website but was unable to do so. The next day back in Guyana, I was recharged the airfare despite my explanation and that of Azul Airlines. Speaking with the TGA supervisor did not help and the 5 emails I have sent to the company requesting a refund have been ignored. I will never fly TGA again and discourage everyone else to do so as well. The worst customer service I have ever encountered.
