Caller: Business Offers

They start by telling you they are a price comparison site for business energy. This is like the 12th time they have called me after me repeatedly telling them I'm not interested and to remove my number.
This time I played dumb, and showed some interest - but before I gave them any info I kept asking for more info about their business. They wouldn't give me any info and eventually said they are telemarketers and don't give that information as it lets people make complaints.
Unbelievable... well actually totally believable considering how they keep calling me.
