In reading other forums its seems as soon you send a Validation letter you are opening a can of worms, the same about a letter stopping phones calls, really that does not brother me, Phone rings I say hello, is this YOUR NAME, so I ask them there name first and last, address, name of company, phone, fax. All the time they are asking My Name still have not gave it to them.
What is a good plain of action to deal with these people, they have been calling for about 2 months.
