Verification

I am trying to use youwave for Android the Whatsapp on my pc, i downloaded it succesfully but the problem is it asked for voice verification and that i will get a call but i have been waiting for more than 5hours no call, i clicked the tab again and they said i am connected but i have to wait an extra 5hours for the call, i did wait but still no call with the code,i waited extra hours and hit the tab and yet still no call, so i re-installed it again and changed the number it still did not call with the verification code. can you help me out? It will be much appreciated. Thanks

N.B. I used the same app on this computer and it did work but I had to re-install it because i couldnt view pictures and that was when I tried using it again but isnt working no more.
