If you are still a IONOS customer after transferring your domain to another provider, it may be due to the following:
Transferring a domain to another provider or between different IONOS contracts is not the same thing as cancelling the contract containing the domain.
Your IONOS contract is therefore still in effect after you transfer your domain to a new domain provider, and in certain cases, you will still be billed.
If you do not want to continue using your contract after transferring your domain from IONOS to another provider, you must cancel the entire contract. The contract will be cancelled at the end of the current contract term, which is displayed for each contract.
