SMS Messages
Dear Apple Support,
 I have the following problem.  My iPhone sends SMS messages to the number +44 (778) 620-50-94.  It is repeated several times a day sometimes.  As I know, it is connected with iPhone working capacity.  It's outrageous, SMS messages are sent without my knowledge and are not displayed in the iPhone Message app.  I suddenly detected it through my cellular company support. Sending messages abroad is very expensive for me.  It were six messages 48 rubles cost (about $ 0.76).  It violates my rights and causes material damage.  Please deal with this problem and compensate for the damage.
 Sincerely
 Vladislav Sautsky
 P.S .: There are screenshots from my cell company app where you can see the payments.  If you need I can send you documentary confirmation of the cellular company.
iPhone 5s, iOS 12
