unable to receive verification codes

I’ve already called T-mobile, the person I spoke with was useless. I recently got a new phone and now I cannot receive verification code texts. This happened before with my previous phone and when I called T-mobile they fixed it in seconds. It was something on my account they had to remove. I explained this to the person I was on the phone with, and she kept telling me there was nothing wrong with my account. She made me restart my phone, change settings, etc. and surprise, surprise nothing worked! I know it’s something they need to fix on my account because I’ve been through this before. She just wouldn’t listen. Now a ticket is being sent to engineering?! UGH this is so frustrating. Who else can I talk to? This should seriously be a 5 second fix and it’s turned into an hour-long process!
