I too have had an unauthorised monthly £10 payment taken from my Amazon card from this company when I booked with Ryanair. Thankfully through Amazon I was able to cancel the arrangement and get my money back. Lesson learned- do not link to discounted flights on Ryanair!
I have had to date 11 unauthorised payments taken from my credit card at £8.00 a time. I have tried to contact the telephone number provided by the company. However after the initial introduction the line goes dead. The email system is much the same.
