i just got a call from this number.
when i answered it was silent.

I just telephoned the 1800 321 321 number tehy identified themselves as Racing and yes promised to remove my mobile number from their list

Persistant, aren't they....again many calls in a day no message left.....and when i tried to return call to see who it was it goes straight to a hung up dial tone. We're a private number also registered for no marketing calls so I don't understand why they are calling. Will look at taking some action against the harrassment if it keeps up.

100% its BetEzy, I rang them today, apparently there is an issue with their auto dialler, if you have an issue just call 1800 321 321 and asked to be removed, you may not actually be a member of BetEzy itself but it has heaps of subsidiaries

After nearly a dozen missed calls (or just hang-ups) from this number, finally a voiceanswers. Identified herself as "Seniors Plus" conducting pain-relief surveys!

receiving call once a day from this number hangs up when answered - in australia
