I just received a call from this number and they did not leave a message.

this number called me and i answered and they just hung up....and i looked out the window and there was a black van that drove off in a hurry.....haha nah that last bit didnt happen....but it is rude of them.

TSA Group is scum.  I've received calls from them everyday for weeks.  After finally speaking to somebody there they refused to take my number off their list.  Do not do business with them and file complaints people.

I too had been called a number of times from this number, like many others I'll not usually answer any number I'm not aware of, however, I did answer it the other day.
The caller was from Telstra (Australia), I'd changed phone companines & he was calling to get me to return, I let him say his piece & I guess he made me a good offer & I returned..

I got a call from this number yesterday and they hung up as I answered and today the same thing happened

my mum showed me this number and we googled it too see if it would come up because this number was writern out on a piece of paper.thanks for the help
