Legal
Right of withdrawal
oneid24 is not sold: nothing is bought, so there is no paid contract to withdraw from.
The rule
A consumer who buys at a distance may withdraw from the contract within 14 days, without giving reasons and without penalties (Articles 52-59 of the Italian Consumer Code, Legislative Decree 206/2005).
For oneid24
oneid24 sells nothing to consumers: the account is free and comes with the Megistone product you use. There is no payment to refund and no withdrawal to exercise here.
For the products that use oneid24
If you bought a Megistone product, you withdraw from that product, on its own terms: you find them on the «Withdrawal» page of its website.
Closing the account
You can stop using oneid24 whenever you like: ask for your account to be deleted from the contact page, or ask whoever administers your organisation.
