Worst app ever – Lebara Talk - low cost international calls Review

I've downloaded the app few months ago and purchased credit through the iTunes Store. I was charged, but I never received the credit. Tried to contact Lebara customer service, but never received a word back. I finally contacted the iTunes Store and received a refund and also apologies for the bad customer service of Lebara! Deleted app afterward: end of story.
