After being able to check the transactions, I figured out the money were deducted from a "mobile keyword company" I signed up with almost a year ago. Even though I`d cancelled my subscription with them, they still charged me for another period. So now I`ll start trying to retrieve the funds from them.
So you can rest easy, Paxum had nothing to do with this, so I`ve still never had any problems with them for years (thankfully).
Also thanks to Ruth for getting back to me within a few hours
