I had a call from this Cold Calling Company , when I asked who they were, they ignored my question , but did admit they were in Birmingham & thought they had my details from a phone company, when I traced back their outgoing number & found out the link to Talk Talk,rang Talk Talk, I spoke to Lynnette Lee, a manager in Talk Talk, Northampton Office (0800 0490948) who was surprised there had been any problem with EMS as they have never heard of any problems or complaints regarding calls from EMS. So if your not happy ring Lynnette Lee & make a complaint.
