In our office we don't pick up unknown calls because of the barrage of telemarketers. Also because all of our business is online, we aren't available for landline calls and all clients have our mobile number that they can call any time. 0420 556 810 calls and doesn't leave a message. Now I see why.

Had a call from this number who would not say who she was but was looking for business owner. I am guessing telemarketer of somekind.

Would not disclose her details!
