edit:  They hang up whenever I answer.

This number calls me a few times a day!!! It's Telstra trying to get me back as a customer. They call several numbers at the same time and if someone else answers the phone they hang up the call with you. And they dont give up!! I tried not answering it and they continued to call several times a day for weeks! I eventually told them to stop calling me only to have them start calling me again this week. I answered the phone and told them to never ever call me again!!

sorry the number was (08) 6210 3210 not 082103210

At least get a call on my mobile from this number once a week, sometimes twice a week. Do not want to answer the number, no idea who it is.

This number rings my phone I answer it and it disconnects straight away. I ring it back a normal land line and it says that my phone is not compatible.

Yeah I keep getting calls from this number.  Have had 3 over the past 24 hours and they hang up whenever they answer.  I was looking to see who it was to report them.  That is funny if it is Telstra, I might follow through with the complaint if it is, cause they are certainly not doing anybody any favours lately.
