Calls for someone who no longer owns the phone number

Every day from morning to evening I am getting calls for some man Abdul Soffi. I don't know who he is I have had this phone for 2 years now and these calls have started in the passed year. I have told the company I don't know who he is I have never heard of this person but they continue to call and ask for him!

I am now at the point that I am now going to report them. the # is 800-599-2346 and then there is another number they are calling me from. Please Help!!
