few days ago I signed the contract with T-mobile thuis and am am waiting for installation at home. I received at home a letter asking for personal details (inc. IBAN) to approve the automatic incasso (machtiging doorlopende SEPA incasso). This letter is not mentioned in contract and would like to be sure it is not phishing.
Should I complete the form and send to the mail address?
Thanks a lot
