Some time ago I tried upgrading to premium, but when I called the specified number the thing ate over 16 euros instead of 4 and then stopped at 59%, since my phone ran out of cash. I know it said to check with my telecom for costs, but I have no idea how to do that. And now you made the diagrams available to premium users only and I have no way to get premium... There's another possible phone to try, but as far as I know, that could eat my cash too...

which country are you from?
we don't have any transaction over 4 euro...

I'm sorry, we can't help you.
Please ask http://www.daopay.com or pay using paypal.

Sorry again

I'm from Bulgaria. The transaction wasn't completed, the cost of the call wasn't correctly detected and it was stopped in the middle of the transfer because the money in my phone ran out... And I can't pay through Paypal, because I don't have a credit card. I'll contact Daopay now.
