Selling financial services

Financial services asking if I want to save money on tax. Aussie guy, asked if I remembered the call we had last year.

Financial services supposedly. Asked me if i wanted to use 40% of home equity. He said we had this discussion last year which we did not. After i terminated call, he had the cheek to call me from 99360321 and pretend it was someone else. Did not say who he was from.

Got called from this number, person on the phone explained services about self managed superfunds/property investment, must just be a place making appointments

I called back number (03) 9936 0322 rang 5 times then goes to busy tone.
