On an Android smartphone you can use call control to block calls and texts from any number. I have used it for over 6 months and it works!
Just google "Call Control" or look for it in an apps list. Free version available, but the low cost pro is much better.
This telemarketer call me daily, trying to sell me viagra, [***] enlargement, sex pills, etc. It's the same people with an Indian or Pakistan accent from Canadian Pharmacy. I have asked them not to call me again, I am not interested, ever!. Yet they still call daily even when my phone number is registered in the national Do Not Call List. I have no idea how these filthy skunks got a hold of my number. Sorry to sound like a racist but these people is making me look down on their whole race. If anyone has any idea on how to make them stop calling, get officials involve, suing for harassment, etc...please let me know how to proceed.
