BAD SERVICE FROM FLYCEMAIR - CHANGING OF FLIGHTS

Dear Sir, I am fuming at the moment !!!! I booked two tickets from OR Tambo to George about 4 months ago for 7 October on Fly Cemair for a flight at 14h00, then about 2 months ago my husband received an email that the flight was changed to 10h00, now today 30 September my husband advised that he got an email that our flight is at 16h00. When I go into their system I, the flight has yet again been changed to 16h20 on Friday 7 October 2022. Now this is not ON - SORRY - You are ******ing us around from day 1. We booked a flight for 2pm for a specific reason, then Cemair changes it to 10h00 without any notification and then I accept it, change all my arrangements for the 10h00 flight and today I am advised that the flight is at 16h20 ????? How the hell is this possible. I specifically want to be in George early on the 7th as I have now changed all my arrangements ??? I need you to investigate this please as I need to get on the 10h00 flight to George, that is why I booked the flight in the first instance. This is totally unacceptable !!!!!! Fly Cemair how long do you actually want to be in business ???? Doing it this way will definately not ensure that anybody will use you again. I URGENTLY AWAIT YOUR RESPONSE !!!!!!!
