More money charged than real bill per month

Dear @Mishra,

welcome to the o2 community!

The bill from 23rd July, 2018, charged you with the initial connection fee along with the tariff for the extra sim card (o2 Free S Flex) plus the charges for your regular tariff (o2 Blue Basic).
The latest bill from 23rd August 2018, charged you with just the few remaining days for the o2 Free S Flex (until 25th July) and your regular o2 Blue Basic.

Which means that the extra SIM card / tariff has ended, and you will only get charged with your regular tariff from now on. With the upcoming bill, things will be back to normal, as it were.

Best regards,
Jan.

Dear @o2_Jan ,

The guy at service center told me card would not cost anything, it is just for promotion and it is for free, i did not demanded for that card, he gave me just with my sim card. Then why i am charged? I visited to service center last month, he said system took more money by mistake and that would be adjusted in my next bill. But instead of getting my money adjusted i got new bill with more money. When i visited Essen service center last week, there was some other guy, who was very rude and not willing to listen me. He just said the guy you talked last time is on vacation, come again next week and only talk to him.

My concern is, i have contract with o2, not a sales person in the service center so more or less rules are same , in details in the system are same then why cannot he help me?

I was never informed that i would be charged money for the flex card, I would not have taken that otherwise. I can visit service again after work tomorrow and ask that guy, why he gave me card when i did not signed any contract for that card.
