o2 My Wired Internet Still Not Activated

About 1 month ago o2 online, I bought an internet tariff called Jungle Leute XL 250 m/bit and I made my contract. Then my first technician appointment was on 06.03.2022 And a technician came from Vodafone, he arranged everything and everything is fine and I just wait for the Activation Date. He Said It Was Necessary And I Planned To Do It And I Started Waiting. My O2 Account Was Closed 2 Days After the Technician. I Have No Idea. Then I kept waiting and until my activation period (My Activation Period was 22.03.2022) 2 letters came, one was a copy of my contract, it was in my landline number and the other was a 4-digit code. but the customer number did not come, I talked to about 4 customer representatives, but I could not get a positive result from any of them, and then when I called the last 1 person, he told me that I had to register the mac ip address of the router and I did so. Everything Is Working Now But I don't have internet access And I don't have a customer number. After o2 contract, my o2 account was closed. and I just keep seeing the same screen so
