For 3 months now that you are charging me CHF 3 for the bill in paper. I have changed and configured in the system in the 4 march to receive invoices by email and I continue to receive them by mail.
You overcharged me CHF12 in an unautorized way.
I have sent you an email requesting this over and made the request on the 3rd of march to change i. See proof attached.
I want to be refunded and to receive the payment slips BY EMAIL and not by post.
Please solve my problem ASAP or I will need to cancel my subscription and file a formal complaint.
