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 Plusnet back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
