After I got three bills earlier today for Mai, June and July, I also received the bill for August. And since I did not use my O2 sim card during that time, it helped a little to understand the bill structure, but added confusion somewhere else.
First of all, I have contract where I am not required to pay a monthly basic fee. Apparently they still charge a fee but credit the same amount on one bill. I suppose this is for bookkeeping purposes. Also I do get a student discount off 15%.
So, on my last bill for August:
Monthly fixed costs before tax:
- Genion S: 0.0084 Euro
- O2 Genion: 8.3949 Euro
(I still need to find out why there are actually two contracts listed).
Credits and discounts before tax:
- 15% discount: -1.2605 Euro
- Credit O2 Genion: -7.1428
So what happened here?
Discount = (0.0084+8.3949)*15% = 1.2605
Discount + 7.1428 = 8.4033 < 8.3949 + 0.0084
So basically first the discount of fee that I actually do not need to pay is deducted and then I receive credit for the remainder of the fee that I do not have to pay.
Confusing. But in all the bills, the remainder is constant at 7.14 Euro, which means in return that on all bills the discount on the monthly fee is 1.26 Euro. Let's remember that for now.
My bill from July:
Monthly fixed costs before tax:
- O2 Genion: 8.3949 Euro
- Genion S: 0.0084 Euro
Credits and discounts before tax:
- 15% discount: -4.9598 Euro
- Credit O2 Genion: -7.1428 Euro
- Connections / Talks: 28.3676 Euro
So my discount should be 1.26 + (28.3676 * 15%) = 5.5151 Euro. But my bill says only 4.9598 Euro. How can this be?
The solution is a always in the fineprint. The 15% discount does not apply for calls to hotline which charge special rates, just like the hotline of my bank. After deducting the money of that one call from 28.3676, the calculation fits.
Yes... it is complicated. No wonder there a special department in the call center that deals with inquiries about bills...
