Numerous calls since 7 Sep 12 with no one on end of call when picking up. Probably computer initiated. Caller ID shows this basic format 08842398XX. Once home phone rings 4 times it stops and it is immediately followed by my mobile ringing in the format 02841585XX also hanging up after 4 rings. These two numbers have to be linked.

Numerous calls - no answer and never leave messages
DO NOT PICK UP I beleive it is SPAM
I am listed on the Do not call register and still get calls.

I have received calls from this number sometimes with a different extension there is never anyone on the line and if i call back it gives a busy single
