There was a previous issue with wiggle a few years ago. Couple of fraudulent activities on my account and got accused of starting a witch hunt when i was a frequent poster on BikeMagic.
It soon became more obvious when a lot of other had similar activity on their account both on Bikemagic and users from here.
My suspicions were correct when I later used a brand new credit card, only used it on Wiggle, from my works internet (Very Very Secured) and I had fraudulent entries passed on that card too.
