Connection Error and cannot reset password

I log-in and a few min later I get a connection error saying that someone else is logging in to my account. I looked at connections and see some from Russia and Texas. I do not live in either of these areas. I have tried to change my PW but the sms code that is supposed to go to my phone is not being sent. I can confirm that the number associated with my account is correct. This is getting frustrating.

After years of playing for free, I finally buy gold and this is now happening. Note that this also happed last week.
