So...I outright asked Andrew Johnston (Australian Tax Office Principal Lawyer, Sydney) WTF he was doing texting me from another number after I blocked his Telstra phone number. He then got another number (via and App he said). I blocked that number and then he got another number to text me and I blocked that too. I finally said FU, I'm going to the police and he finally stopped. I was freaked out big time! It's hard to know how to handle this type of behaviour. E.g. Do I now try to placate and befriend this person in order for a long-term better outcome or do I run for the hills and have them do this stuff again from a fourth phone number. OMFG. I moved a long, long, long way away from him as soon as I thought I had him lulled. Thank God it finally seems to have stopped. He told me his ex wife was a lunatic but therein lies the problem...I think it may have been quite the reverse.
