Don't touch them! They caught me with a Google-branded popup offering a new phone in return for answering a questionnaire. They then wanted 1Euro to cover postage for the 'phone. It was only after harvesting my credit card details that I discovered the 1Euro was a charge for being entered in a sweepstake and they had used my card details to sign me up for a monthly subscription. To add insult to injury, they then promptly charged my card with £7.50. Luckily, they're now blocked and I've organised a charge back from my credit card company. On investigation, they're based in the Czech Republic but use a New York number for what they laughingly describe as 'customer service'!
