You can block phone numbers on a cell system the same as on a landline. You might need to call customer service for them to do it but it is possible. I have done it so I know it can be done.
But see these people not have any type of conflicts with us and why they do this. and the most hypothetical thing is they still call when they know they cannot speak like us.
I knew they will be like some scammers. Thank to Christ that i got in touch with one of my attorney and he said me they are scam. They fool you like giving you the information about your bank or ur SSN or case file number that is all fake. One of my friend also received call whose name is Robin Taylor and they gave him same case file number as mine.
Now this is just a common sense that how two different cases have same file name.
