Time wasted and money lost... I recently booked the G Adventures Classic Colombia trip. I initially planned on booking directly with the tour company but when I logged into my Tour Radar account, saw that the sale price was cheaper than with G Adventures, and saw that I had an additional travel credit of about $213, I decided to change and book with TR, only to be told that credit was a glitch in my account. The price that I had seen when I made my request for a 48 hr hold for a spot on the tour, which included that $213 credit, was not honoured, which I think is terrible customer service. For all the time I spent chatting with agents on the website, talking with them on the phone, and consulting emails, only to not have that additional saving, I should have booked with G Adventures directly. One positive thing I will add is that the last person I dealt with on the phone, Günel, was kind enough to find me a promo code that somewhat compensated for the price difference. Again, very sub-par customer service that will make me seriously reconsider booking with TR in the future.
