Home-owners are being warned not to fall for salespeople ringing them out of the blue trying to sell mattresses to them.
Concerned resident George Goudie said he had received one such call and was worried a vulnerable person may be taken in.
The retired BBC engineer said: “I received a call last week and they said to me they were coming into the G61 postcode to demonstrate mattresses.
“It is a cheek as they asked for me by name. I don’t know where they got it from as may wife and I are on the telephone preference list, which is supposed to save us from this type of call.”
But what worries Mr Goudie more is that there are quite a number of older people in his street and the area in general who may be taken in.
He added: “This is the first time we have had such a call, but we have had people coming to the door asking if we want our roof fixing.
“I jus want to pass on our experience and warn others that they may get a call like this. I just politely, but firmly refused the offer.”
Diane Campbell, director of governance and regulation at East Dunbartonshire Council, said: “Cold calls can be irritating for us all. Anyone who receives these sorts of calls should simply hang up, telling the caller they aren’t interested.
“The council is also in the process of trialing a system called trueCall to prevent unwanted calls without blocking genuine ones. It can be used in a variety of ways and can be set up to meet the needs of individual consumer. Residents can also report any phone calls or callers to Trading Standards on 0141 578 8813.”
