Open new contract by miscommunicate with the hotline agent

I called the customer service to change to post paid on 7.03.204 but didn’t receive the sim card. So I called again that if it is possible to change that post paid contract to cheaper contract on the 26.03.2024. I called the hotline again yesterday because I hadn’t received the sim card and my current sim card was deactivated and another agent said I placed the order for new sim card for new number so I told him that the agent on 26.03.2024 misunderstood and I cancelled new number yesterday. I got replacement sim card for the more expensive contract yesterday at the store from his advice. 

However, I checked on the o2 app and it showed that cheaper contract sim card ready to be activated. I would like to make sure that it is cancelled and I will not pay for it. 

Thank you so much for your help.
