Although TourRadar provides fast customer service, when it comes to payments and money matters it is pretty messy. This is especially likely to happen if you request a change, such as single supplement etc. They can mess it up and pretty much charge you whatever they want and not what you see on the screen. I booked the Bolivia, Argentina and Peru Adventure they charge me approx. $9000 instead of the approved approx. $7500, leaving me in a foreign country with no money. It took me three days in the bank to adjust the error. It was the third time the company overcharged me by mistake. In the previous instances, I had placed a cap on my credit card so they could not get the money. I suggest when one makes a purchase from them should place a restriction on the card. Apart from that the discounts and rewards are attractive.
