The initial tour booking was satisfactory although slow and I had to chase it up. It said "Instant Booking" but I had to wait for confirmation. A follow on tour I wished to book and with the same tour company as the first, only had date for 6 weeks ahead, I inquired using on-line Chat. I receive a curt response that "We do not have dates for your trip". End of story and effort. With an online inquiry and emails the provider company, Tangol, quickly prepared a quote and the booking made within an hour. So little effort or to lazy lost your company my business and I lost the Valentine's Day Discount and or the emailed 3% discount. I would have looked at booking flights through TourRadar but will go elsewhere now. I use Firefox browser, none of the Links on your website would work, but worked fine when I changed to Edge. Similarly the email links would not work on my MS Outlook email program but when I forwarded them to my Gmail a/c they worked fine. I don't have an explanation but it was very frustrating. Any other email or website links worked normally - it was a problem specific to TourRadar. Hope that is some help to you.
