billing and texts from service provider

Hello,

This week. I have paid 3 small amounts in 2 popular games from the Apple Store. I always get a text from my service provider about the amount I’ve been charged due to me using Mobile Number for payment in settings.

However, suddenly I’ve gotten a text that a payment was successful with an amount that’s rather high. I did not do this myself. It always gives an Apple ID transaction code so I went to see in the apple billing site to review my history. This payment was no where to be found and I’ve no clue what it was supposed to be spend on. As i use mobile billing (on a pre paid sim card) this amount can’t even be spend cause i don’t have this amount on the number..

Now these questions go through my mind like, was this message a scam regardless of it coming from the usual service providers number? Was there an actual attempt to pay something? Do I need to do something/contact anyone? Am I in danger regarding my Icloud/financial stuff?

Thanks for anyone replying!

ps: A day ago i also received a text stating I got partial refund for something I actually did pay myself (did not request a refund whatsoever). Though I did not get a refund at all. And the payment is actually still marked as pending in apple billing..

Im confused…
