Rude operator, harassment

<p>I just got a call from a rude operator from Elite Mobile. He demanded my wife's cell phone number and when I refused to give it, he called her regardless (seems he had the number in the first place). When I answered my wife's mobile to say we are not interested, he hung up. But then he kept calling her number and everytime she picked up there was a few seconds' silence on the line before the operator hung up. He keeps this up repeatedly every 10 seconds or so (as at Friday 2 Sep 15:45, for the past half hour now). There is no called ID so we can't block his calls. I repeatedly called Elite Mobile's number (***) but when going for option 5 ("speak to a consultant") the line goes dead. This is the worst case of unsolicited electronic harassment I have ever experienced. </p>
