If so, are their topic about 'banking??', for safety sake, you may check with your bank too and ask whether they (your bank) provided your information to the research company
I've 1 experience that I closed the account in XX bank, then a research company called me & said XX bank held a group discussion & would like me to join (this research company got my information from XX bank)...then I join the group discussion, they are researching why some customers (like me) close the account in their bank.....
