For context: I move out of my old apartment on the 31.03.2023 and did a new contract with O2 for my new apartment, letting them know to cancel the old contract, but I’ve been charged since then, the amount for the old contract, and the amount for the new contract. I’ve been calling multiple times for this issue, but they just say it’s done, and the next month, I get charged again.
I am tired of this situation and want it to be resolved, plus get the money they have been charging unfairly from me since then.
I am not even sure of which number is the contract I need to cancel, since both show online as my new address, but I can provide the address to confirm it.
