Sketchy

I added a service to a new location while keeping service at existing location. Somehow they shut off service at existing location. I called to restore it. I was under a 2 year promotion for a free modem. The agent said he could no longer put that promotion on my account and I would have to pay for the modem. I told him that it wasn't my error and it needed to be fixed. He tried to tell me that I approved the account to be modified, so it indeed was my fault. I did no such thing. Absolutely not. I asked to speak to a higher up. He asked for my phone number so I could receive a call back. I provided the number and received a text message. It was a one time code good for 15 minutes. It said, Do not share this code with anyone. We will not request this code. I told the agent the text specifically told me not to tell him the code. He insisted he needed the code to request a call back. I told him I was not giving him that code. He provided me a website to click on to instead, which came up in error. He then sent another website to request a callback. I told him I was unable to do it, so he told me he could just request a call back for me anyways.... why did I just have to go through all of that if it was so simple for him? He had sent me a message and not even 30 seconds later he disconnected from me saying I left the chat. 20 seconds after that, I started receiving several text messages asked for the one time code. I'm talking 7 or 8 code requests within a few seconds. Something just doesn't seem right. And then the sketchy part of our conversation history seemed to vanish. But the not sketchy parts remained.......
