I dont know if this is the right place to post this, I am constantly getting calls for some courier company on my mtnl landline number mon - sat which has made life miserable to say the least ... my number is 12 years old and hence cant change it .. I asked one guy which number is he trying and problem is that the numbers are identical only the wrong number has one extra digit and is a non mtnl number .. my question is can i do anything to stop this or i have to learn to live with it ?? Please advise ...
