I created a UseNeXT account not long back and after creating the account, I went to paypal and did my usual check of seeing if it was a recurring payment setup and to my finding there was none, so I had thought I was safe. Well that was until a few hours ago when I just noticed that I've had a paypal charge of £79.84 or so and as a student I simply cannot afford that.. I have my flat to pay for and food.
I've contacted UseNeXT support and hopefully should get a reply soon, so I'll have to comment on what happens.
*EDIT*
As a update, they've replied and fortunately have been very forgiving.
Paypal needs to easily display what you have transactions that you can be charged from. I looked for it as soon as I opened the account and saw nothing when clicking "Details" on a transaction.
