Customer Service and Cancellation

i had booked ticket with cheap o air now because of my medical conditions i can no longer travel at the selected dates i have been calling and chatting with the customer service staff for over a week now but i am getting no results at all its difficult to recah the manager if you want to complain about the services and the supervisor Kanchan and customer service Rep Paulin are Rude and Misleading customers and worse customer service Really disappointed !!!!! if there was a negative i would give to them. they serve customers with " I DONT CARE" attitude. its been 5 days from Friday 7th October my query is still passed from dept to dept. I was given a quote by zackery for cancellation which i was happy to pay the cancellation fees of $100usd and get the refund but the greedy staff now changed the statement and claim there is no refund??? HOW MISLEADING !!!. they give me a wait time of 12hours the first time for the manager to call back and i got this rude supervisor who does not even care to hear out the customer !!!. than another wait period for 6 hours was given before a call back than another this is a total of 1 week and my issue is still not resolved....REALLY DISAPOINTED I would never recommend this company to anyone ....
