Sefton Central Labour MP Bill Esterson has called for greater protection for pensioners and vulnerable people from door-to-door salesmen after a Maghull man was left with a huge bill for windows which he didn't need.
Kevin Stark's family were outraged when they discovered that the pensioner had been landed with a bill for £5,918 after he signed up for new windows at his Maghull home.
But the 77-year-old, who is still mourning his wife who died in January, had initially been told that the bill would be £2,871 for two windows.
After discovering the full cost of the bill, Kevin's family immediately complained to window company Everest and turned to MP Bill Esterson for help.
Kevin said: "I signed up for the windows after I had a knock on the door from a salesman. He told me I needed the windows and he could do me a good deal.
"I signed up knowing what it would cost, but then when I received a letter confirming the work my family realised the bill would cost much more because I had signed up to the monthly payment scheme.
"I was shocked by the cost and really didn't know what to do next."
Kevin's daughter Debbie Harris said the whole family was shocked when they discovered that their father had been targeted by the salesman.
Debbie said: "We really couldn't believe that a salesman from a reputable company would target anyone who is clearly vulnerable.
"My father is 77 years old and is still mourning the death of my mum who we cared for in their house until she died just a couple of months ago. he is clearly a vulnerable person.
"But the salesman still persisted. That in itself is very wrong.
Bill said: "Lots of companies have a policy not to target older people, but there should be more safeguards in place to stop this kind of thing happening in future.
"I will raise this in Parliament as I have been contacted by a number of people throughout the constituency who have had elderly residents who have been targeted in this way.
"I would warn other older people in Maghull, Melling, Lydiate and the rest of Sefton Central to learn from Kevin and not sign up to anything from anyone on the doorstep.
"Everest has clearly seen that there has been a problem and reacted quickly to apologise to Kevin and his family. Not every company or doorstep salesman is as reputable and will take action like this to set things straight."
Kevin said he had learned a valuable lesson but he has a plan for dealing with door-to-door salesmen.
Kevin said: "If any salesmen knock on my door again, I'm just going to chase them away in future."
