SMS verification code error

I did everything the game masters said to do and whenever i try to get on call of duty modern warfare and it gives me the error to quit and verify i can’t verify because the sms doesnt get sent to my phone even tho its the right phone number. So devs work on this because this is absurd and ridiculous you guys make so much money to have lousy bugs like this to occur and on the second thing add a phone number for customer service we dont have all day to wait for you guys to reply its been about 2 hours no reply.
