De Lijn says that it only conducts promotional campaigns through its own channels. Furthermore, a photograph in the mail contains a number of tell-tale discrepancies. For a start the bus featured in the photograph wasn’t a De Lijn bus. Secondly multi-journey tickets with a value of 50 euro don’t exist for De Lijn and thirdly the chip card featured in the mail is only used for season tickets.
It is likely that the mail is the work of internet fraudsters. Anyone that receives the mail is advised to inform the authorities at the following e-mail address: firstname.lastname@example.org.
