Caller: Probably Clever Contacts

I've received a number of hang-up calls to my landline over the last 10 days or so, from a bunch of apparently related mobile numbers. After receiving the most recent today, I rang that number to check who it came from. I've already lodged a complaint with the Do Not Call Register. If you are being similarly pestered by these people, you can complain direct to them as well via their website.

They didn't leave a message, but I suspect that it is a marketing company, as there have been a number of hang-up calls from very similar mobile numbers (only differing in the last three digits) over the last week or so. I'm on the Do Not Call register, which does not seem to provide much protection from nuisances like this.
