Caller: one of the telstra dealer who looks after nbn

I recieved a call from a guy who told me that my business site was ready for nbn transiition and then he guided me about the plan and offers and benefits of the nbn and helped me to get it installed.He even told me if i have any issues you can reach me directly and which even meant to be right , as my internet went down and i called him up and he got that fixed for me.
Really Helpful.

I called back number (03) 9002 4050 spoke to a guy who said I've reached Telstra Business Centre.
