Austria: Orange's Datenpaket

[9eor9]

WARNING:
The conversion does not work with a data SIM!

I checked the balance (balance was zero) with *101# and received a message:

"Sie haben noch 0 gratis Einheiten (Minuten/SMS). Bitte melden Sie sich zu bob Vertrag an oder laden Sie einen Bon auf, um bob als Wertkarte zu nutzen"

I bought a bob voucher and entered the code. Answer: "bob bon Aufladung nicht erfolgt, spezieller bob bon nicht aufladbar" (failure).

Then I called the customer service 0043-680600680 and the lady explained me that a data SIM cannot be recharged with a voucher and that the tarriff of it cannot be changed. I replied that I only did what the bob message had recommended and that they ask their customers impossible things to do.
She was not able to send me a free voice SIM that I had asked for. Then she suggested to write a letter to bob, to explain the whole matter and to again ask for a free SIM. That I'll do...........
