My account had just been hacked recently. I answered some survey and I've got it back and thought using mobile verification would help preventing it from getting hacked again. But I keep getting text for the 'verification code' that I only requested once, and it is the same text over and over again. I've already received more than 10 same SMS for the past 24 hrs. Will I be charged? I tried to remove the mobile verification setting, removed my phone number but I still received the same SMS. Is there anything I can do now?
