I've been contacted on my cellphone twice this morning by Altech Netstar, trying to sell me their vehicle tracking deal which apparently is on special for this week only.

The first time I listened to the deal. The second time around I was more interested in where they got my cellphone number from, as it's not exactly widely published.

Apparently they got it from a consumer credit database.

I've just renewed my cellphone contract.
It seems this pops up on a consumer credit database.
And this is where they got my cellphone number.

So is entering a transaction that results in a credit profile listing update constitute permission for unsolicited tele-marketing from 3rd parties?
Is this appropriate use of a consumer credit database?

The caller from Altech Netstar seemed to think so.

I'm not quite as convinced...
