TS Marketing Research - spam?

Don't engage with these people, phoning to ask personal information about your personal expenditure saying that this is Marketing Research. I asked for the full name of the company and the web address whilst on the call and told the caller that I was googling her company to see what this was all about before divulging any information. She couldn't give me a straight answer or a web address, but said that it was TS Consumer Insight which does exist and I asked the caller what the TS stood for on the website and she said 'Total Sales' - which it actually doesn't. I told her that I would not be divulging any information as she couldn't get the name of her company or website right. She also mentioned that they are calling 'all citizens' in the country to do consumer research, that was a red flat anyway - how could she possibly be calling 'all citizens' - but she insisted that was what she was doing. It probably is a spam or scam call. Don't give any information.
