How scams that copy retailers work
Age UK says callers impersonate Amazon customer support, offering fake discounts on a Prime subscription or saying there is a problem with a payment. Ofcom advises checking any account through the organisation’s own website or app, never a link or number from the caller.
This could still be a scam call
Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call Post Office back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
