Received 2 hang-up calls today from same number (02) 8989 8302. Called back, expecting it to be a predictive dialler checking when the line gets answered (for somebody else to call back). It was not, I rang 5 times in total & each time the phone rang until someone pushed the 'reject call' button. It was NOT automated as it took a different amount of rings each time before they rejected the call

I called back number (02) 8986 8302 rang once then gets disconnected automatically.
