Interestingly enough I serched the previous owners name. His business was known as Quantin PTY LTD. So I've managed to find Quantin Property Maintenance. I tried contacting Raimond via that also. Exact same type of business, no one answered the phone and it went to a msg service. It said that they had 27 years experience in the area but clearly not because there was no written testimonials or anything about them anywhere. It just didn't seem to add up. THe guy is obviously a serial skammer. If I were you Ken if you paid via credit card, quickly lodge a transaction dispute I'd do it regarless if they fix the system. These android units are clearly some sort of prototype.
