(Migration process, sudden disconnection and any other reason) and this situation has been last for 28 days or more, could I ask for a termination of the contract? Will I need to pay for the rest of the contract?

5.Do we need to return the LiveBox in the case of termination? Will it be required to be return in its original packing?

6.In any situation, will asking for a MAC code equalvent to cancel the account?

2. If you have been without service for such a period, you would be entitled to a refund for the period of inactivity. You may have grounds for termination of the contract if they offer no sign of resolving the fault, but it's probably case specific.
3. If you signed a contract agreeing to pay
