I called back number 0409 248 790 rang 5 times then goes to busy tone.

Global telemarketer. Listened to the first call, said he wasn't a telemarketer, but would I like 'free sample'. Said No and hung up. Later that day, same number, different person, Then everyday since then . . and not only the same number, this company use different numbers as well. Several calls everyday on the landline. Unable to block the call. We are on the do not call register, but they get around this by saying they're not telemarketers, and ringing before 7:30pm. How can you deal with these scam artists once and for all when they are officially operating within the law, and then they just ring again using a different number?

Has called me 4 times in 2 days. Never leaves a message. Blocked!
