The number 020 4393 3633 is a fax machine, which repeatedly rings my mobile telephone number. The calls are presented to my message bank if not answered, and increase the number of messages left on my service. recovery of these message cost $'s. The repeated calls are annoying to say the least. I have made complaints in the past regard this fax number calling mobile telephone. Unless this is resolved, the next move is a complaint to the A.C.M.A.
