When using the account number given in the contract from the “Identifiant client” to register for the online bill, I receive: Numéro de compte invalide.
How can I receive the correct account number?
When trying to use my tango app and register, I receive “invalide phone number” when using either the phone number registered in the contract or the Tango FIX number.
When sending a message with “compte” I don’t receive a reply.
Please help.
