A PENSIONER is warning Boston residents to be on their guard after an alleged BT caller rang her asking for her debit card details.
Kathy Goodacre from Boston, received the call from an international number claiming to be BT.
The man on the other end of the line said he could get her discounts if she gave her debit card number.
Mrs Goodacre refused and contacted BT.
She told the Target: "The adviser said they would be able to knock 20 per cent off my bill if I gave my debit card details. He asked for the long number on the card. I would not give it to him. I asked for a number to call him back on, which he gave. When I called the number back I could not get through.
"I really want people to be vigilant and be very careful. Don't give out any details and call the company that calls you back to check it is real."
BT confirmed that this scam does happen and said: "We advise customers never to give out any banking or personal details over the phone unless they are absolutely certain who they are dealing with.
"A BT employee will be able to give the customer their employee ID number and an 0800 number to call, where the customer can check that they are who they say they are.
"If you're in any doubt whatsoever, always play safe and double check. Free advice on nuisance and malicious calls is available for BT customers from BT's Nuisance Call Bureau on 0800 661 441. We would advise anyone concerned that they may be the target of a telephone scam to report the details to the police or trading standards."
Lincolnshire Police are also urging everyone to be on their guard against such scams and never to divulge personal or financial information to cold callers.Alternatively, hang up and call the number on a statement from the company.
