Appaling Customer Service.

They'll do whatever they can to get out of paying you what they owe. Very dishonest people. Must be extremely vigilant if you use them!

Only sign up if you believe you are going to get quite a lot from the 10% cashback. The £15 monthly bonus gets swallowed up immediately by the £15/month fee. So make sure you use it every month and ask yourself if it is really worth it.

Also, on various places like The Trainline, you can get a free one month trial. Use it three times and you can get £15 monthly bonus twice and £16.87 welcome rewards, without paying them anything. Just make sure to remember to cancel in time!
