Caller: Aussie Home Loans

I received 5–6 calls from Aussie Home Loans over two days. They did not leave any voicemail messages.
I answered one of the calls and informed them that we are not interested in refinancing at the moment. However, just two hours later, I received another call from a different broker asking the same question.
The following day, I received two more calls.
This level of repeated contact is excessive, especially after I had already provided a clear response.

This number called me twice in a day. I missed the first call in the morning and no voice message was left. The same number call again in the afternoon and I picked up but no one spoke anything from the other side.
