VERIFICATION MESSAGES ERROR / NO ACCESS TO SET UP PASSCODE: (VORCC02) - I'm a 1st Time Client

Re: VERIFICATION CODES DON'T WORK AND I CAN'T SET UP PASSCODE AT ALL.

I transfer from another mobile company to AT&T in hopes that it will be amazing and everything would be working to perfection. Sadly, I have encounter several issues with the process of how things are done. Specifically because I wasn't informed I needed a passcode and a random representative set it up through a call, and I don't know which one it is. I don't think the representative should have done that at all. Now, I been calling the call center to ask information on the account and every time I try to validate that is my identity through the text messages that they send, they say it's incorrect. When I go on to also try and change my passcode it shows an error: 

"Be sure you entered the code correctly.  " 

One of the representatives made me feel like if I was dumb because "it seems" I couldn't read 6 numbers; when I was trying to explain that those were the ones I received, the representative kept asking if I was sure I'm reading the right texts. I requested help because I can't fix it and it seems that nobody else knows what's wrong or what to do with it. Things I have done OVER and OVER:

I have cleared my cache several times, I have changed my browser several times, I have changed from computer 3 times, I have used an iPad, I have used the mobile app and nothing seems to be working. The verification error keeps showing up. I'm not using roaming and I'm in the US, not abroad.

I want to know if anybody knows why the messages are not synchronized to the phone; the numbers sent are not the right ones. I called several times today and couldn't verify it's me and I just bought my phone today. This is my first time in my whole life that I have enrolled with AT&T and so far, it's been horrible, so I am begging anybody to help me fix whatever this message is. By the way, I don't think that representative should have created the passcode for me because now I have no idea what it is, the representative didn't tell me what it is and the verification codes that are sent to my phone does not work.

This is very frustrating and I definitely need help, I don't want to regret my migration.[edited for privacy – please do not post personal information]
