Check the request through another channel.
If a message asks for payment or personal details, open the company’s app or type its known address yourself. Use a phone number from the official website, not the message. Do this even if you really are expecting a parcel.
Pressure, impersonation and an unexpected request.
Scammers may pretend to be a bank or delivery company. They may claim there is an account problem and pressure you to act. Correct spelling and a familiar logo do not establish that a message is real.
Try it together over a cup of tea.
A fictional example: “Your parcel is waiting. Pay €1.90 today.” Ask your relative: “Where would you check whether this delivery is real?” Then find the courier’s app together. There is no need for a score or a competition: the useful part is trying the next step themselves.
Agree on one sentence.
“I’ll check first, then get back to you.” Use it as your family agreement when an unexpected payment request arrives. The free homepage example lets you try three situations without an account. For regular repetition, take a look at SMS practice.
