A few weeks ago, an O2 agent called to discuss my expiring contract. I was at work and couldn't fully grasp all the details, but he offered to continue my current tariff at a reduced price of around €19. I agreed to this, though I now wish I had inquired about the cost of unlimited data. My main question is: will this new €19 contract automatically take effect with the same tariff once my current contract ends, which should be around September? Additionally, the agent presented a German contract verbally, which I did not fully comprehend, and I was prompted to say "ja" three times. I am now seeking confirmation that the terms of this new contract precisely match our conversation, as I am concerned about being bound to terms I didn't understand.
