I thought I was going through KLM website so booked my flight only to find when the confirmation came through it was Fare Geek. This started alarm bells going because not only had my return dates changed they wanted more money to 'fix' this problem. When I received another email 6 hours later telling me that they could not take payment as my details were incorrect and could I please email them a copy of my card front & back AND government issues identification this really got all the alarm bells ringing so I contacted my bank to cancel my card. This is NOT standard practice,
