There is no stopping them, one of their miscreants said to me- "if you buy their services the calls would stop", - arrogant eh! Well, I bought me a whistle, one like those used on the football game field, with the rotating ball inside, gives an extra loud shriek. When they called I'd give them a real loud BLAST as loud as I could.
That seemed to have stopped them so far.
Probably need to expand this as an anti scam campaign.
Just received a similar call. Thanks for the posting . I never answer my cell if I don't recognize the number anyway. This saved me the effort of following up. Am blocking that number.
The same thing has been happening to me. How can you stop them from calling? Next time I am going to answer, get as much information as I can and threathen legal action.
