Total and utter rubbish charges for non connected calls

I use the following apps:

1. Skype
2. Vonage
3. Mobile VoIP
4. VoIP one click

All The above a brilliant and I cant fault them. I was testing this app (I am a tech journalist) it charged for two calls that did not connect using the bulk of the credit to pay for ringing tone and on a third call the other party could not hear me but I could hear them - this app is a total joke and the one call that did connect to check voicemail was useless because it did not generate tones!

A truly horrible and dysfunctional app and there are no excuses because there are loads of great VOIP apps in the store which I dont use that are great based on friends reports e.g Truphone etc but this app was a nightmare. AVOID!
