Getting 5-7 calls per day from my own phone number (with the number 11 added to the front of it). Web searches show others have similar issue, but have only seen guesses at the cause. Virgin is refusing to answer my emails on this. Just say they need to send this to a higher level. I ignore the calls and they go to voicemail, but strange how none of these calls is being charged to my quota. Thought about calling back, but am afraid that the "11" might make it an international call that is some scam costing me a bunch of money. This phone number is only known by a very small number of close people. This is not some prank. Can anybody share what this is all about?
