When I tried to book my trip my credit card wasn't accepted. Knowing that this wasn't possible, I contacted the Chat line operator who would only tell me that the problem was with Visa and would not give any details other than to say that your Head Office was in Vienna and it was closed at this time and that I needed to contact Visa. I started to wonder it your company was a scam because I had never experienced not being able to pay for something because a Head Office was closed so I called Visa and they said the problem was at your end (Tourradar) and that my Visa should be accepted but they couldn't give me any details other than to say that maybe Visa had had problems with your company in the past. I was able to book the trip after my phone call to Visa but then wondered if maybe my payment had been blocked because Tourradar was financially unstable. I spent a restless night worrying that I might lose my deposit and wondered if you took the rest of my payment in June, was Tourradar having financial difficult. Surely there must be a better way to have handled this situation? This morning I received an email from Overland Tour Company so I am somewhat confident that the trip will go as planned (I hope).
