Welcome into the Community and thank you for posting into us.
I would like to help and certainly when there's charges from these texts, their never fun. I can see that you have had some really helpful information from AlexKid and would love to know how you got on after following this?
Also if the texts were not of your doing, you can usualy claima refund back from then if you're able to identify them. i hope things work out for you and please take care.
