P. Krishna Kumar, Kerala, Alappuzha — justdial calls me frequently

I receive calls frequently from justdial. I haven't availed any of their services. They ask me whether i am interested to enroll as a lawyer in their directory. At least 50 times i said, i was not interested. Still they repeatedly calling me. It is not possible to block their number as they are calling from different numbers. I am no more a lawyer. Please avoid calling me.
