i’ve been receiving unwanted calls since quite a few days, i am trying to ignore it but some times i just could’nt resist myself. when i say unwanted calls, i mean calls that the customer care executives keep doing, the insurance companies and the credit card sellars. they frequently keep calling and when they call they take way too long to explain things. this pisses me off. need a software that can help me make ’em believe that i have problems with my network, whereas it is done on purpose by me. let me know some more knowledge of cellphone blocker and how to implement it on my network?
