If you receive a text message saying you have missed a DPD delivery and ask you to make a new booking by clicking a link that goes to "* dpd.missed *3k9j.info" or "pdp.missed*.info", it is scam. The dpd scam text is being sent by scammers who are attempting to trick their potential victims into clicking the link in it that goes to a phishing website that steals personal and financial information.
If you receive the dpd.missed scam text, do not click the link or follow the instructions in it, just delete it.
