TV Antenna Technician lied and all of them rude and arrogant

I had TV Antennas Australia (trading as Andrew's Home Services) mount a TV and install an antenna in my rental property for my tenant on Friday 9/2/18. He “checked” the reception and I told him I wanted it installed in the ceiling not on a the actual roof. He tried to talk me out of it because it was easier, I stood my ground and paid him over the phone with my credit card. They had to come back Thursday 15/2/18 because of bad reception. The installer told me I need to install it on the roof and I had to repeat it at least 15 times I didn’t want it on the roof and I paid for a working antenna in the ceiling, after a lengthy discussion he said it would check the cables and move it around but that it should be installed on the roof, to which I replied I was not having this discussion again. Rang the office and was told the owner\manager would not be in the office until tomorrow, explained again the issue and got an attitude and “the technician is a star” and it need to go on the roof. Again I said that is not what I paid for and if it wasn’t going to work in the ceiling they shouldn’t have taken my money. Then I suddenly get told that the manager “has just walked in” and would call me back and hung up without taking my number.

Manager rang me after getting my number from the tenant, same merry go round. Repeated myself again, this time the manager accused me of lying about wanting it installed in the ceiling to which I replied that you how could I be lying if it’s installed in the ceiling, it’s not like I got on the roof and took it down and put it in the ceiling myself. I then repeated that if they could not install it as required to refund me the antenna costs as they have not install what I wanted and I would get it done by someone who could. He refused and said they were trying to give me a solution again which is other that what I actually bought! I advised I would report this to Consumer Protection which I have. BE CAREFUL, promise you they can do what you want and then deliver what they want!
