So I had bought a return ticket to Colombia and decided to cancel the return part of the ticket. I called Get a Flight and they wrongly advised me that I could get £320 back. I checked this several times with different agents before committing to cancelling the return ticket. When I made the call, they told me that I could not get any money back. Unfortunately by then I had made arrangements to stay in Colombia based on knowing that this extra expense would be offset by the £320 refund. I should not have believed this company. They are not serious and completely inconsistent with the advise they give. They feel no scrupule about lying to their customers. They will simply deny the truth and get away with it. Manager today was the same. I will never use them again and advise you not to either.
