thank you very much for your question. My name is***** am a computer expert since 17 years and I will be assisting you today.
Where you able to answer the other questions Google asked you? The verification code via a text message is just one of at least 3 that need to be answered correctly. Otherwise it will give you that message you are receiving at the end (that it can´t verify that you are the legit owner of the account). Please let me know.
Thanks for your patience and best regards,
