Call at 8.25 pm on my landline. I answered and said hello. It took a short time for someone (male with accent) to come on the line. The male said he was from a travel company (did not get the name) and asked if I remembered filling out a form. I said that I never fill out those forms (I haven't seen one in years.). He then said sorry for the call and ended the call. I was expecting him, as has happened in past, suggest that the form may have been filled out by a relative or friend. This appears to be the method they use to justify the call as legitimate and not a "cold call". I also expected, as has happened in past, for him to try to sell me holiday vouchers.
If you get one of these calls I suggest you say "No thanks and goodbye" & then hang up.

Caller: Unknown male

Caller seemed surprised I actually answered. Then he started asking questions about me. I gave him nothing and hanged up.
