For pensioner George Haynes, unsolicited marketing calls are as unwelcome as they are unwanted.
He regularly receives calls from companies selling things like insurance or offering compensation, and has been known to receive up to nine calls a day.
He's not alone - figures show almost three-quarters of landline customers have had a call from a marketing salesperson, and almost half of us have been on the receiving end of an automated 'silent' call.
Today MPs debated whether new laws are needed to crack down on so-called 'nuisance calls' - as Ian Lang reports.
Earlier today ITV Cymru Wales spoke to John Michison from the Telephone Preference Service and asked him why unsolicited calls are still reaching our homes, even with an official opt-out system in place.
@itvwales our answer machine says"any nuisance/sales calls, please delete our number from your database"we don't answer our phone-its wrong
Caroline Harry on Facebook: I have caller ID on my phone. If I don' t recognise the number I don't answer. If its important they can leave a message and I call back.
Janey Stevens on Facebook: Nuisance calls happen everyday, at least three times a day and more sometimes...some are silent, some are those wretched recorded messages, some are people trying to sell something...it is irritating to say the least.
Geoff Owen on Facebook: The annoying ones are the automated messages. I'm sorry if you're going to phone me, actually get a human to call me and not play a tape at me.
A South Wales MP has called a debate today on the problem of nuisance phone calls.
Vale of Glamorgan MP Alun Cairns says many of his constituents are plagued by the calls, which range from attempts to sell you something you don't want or need, to an offer of compensation for an accident you have not had.
He wants action to clarify who is responsible for dealing with nuisance calls, and crack down on companies which offend most often.
At the moment responsibility is split between Ofcom, the Information Commission and the phone companies.
He wants to see a code of conduct to close off loopholes found by companies, such as speaking to people using the Telephone Preference Service by saying they are surveying them, rather than selling to them.
He is also calling for a solution to crack down on companies registered abroad making calls.
