Well, considering Bob posted in 12, he's probably unlikely to see your post. IF you're answering all the calls from this number in any way, you are likely to keep getting more. It's a way to get on your nerves since that "stop calling me" is not understood in their language. What they will understand is calling a number that has no kind of answer eventually becomes a waste of their time. Try that if you're able and see if they stop. Some pests such as breast cancer and hero charities are like that. As long as they're not getting anything for an answer, they'll get disgusted.
I started to proceed through the link you have posted and was directed to a site which had what appeared to be hindi writing so I backed out before the page loaded
They want to get back at us normals by turning us into their slaves. Don't fall for it! Give them nothing... I would supply more info but it would just be translated into braille and used against us!
