No means of contact and no emails.

I wish to change my mobile number to an off s**** number. I cannot access my account because i cant get the OTP so i cannot change my mobile number. I cannot contact you because i am in the Netherlands and 087 numbers are barred. There is no international contact number. I am not receiving my emails and i can do absolutely nothing if i cannot contact you. I VERY URGENTLY need assistance. My mobile number is +***3.
