Waste of money

I just bought this app and tried two number I received calls from this morning. Got blanked on both. Dont waste your money. Google works fine for spam. In my case I make a lot of calls to perspective clients & if Im not at my desk I dont know whos calling back. I thought this would help. Wrong!!! I want my money back!!
