Hello O2, when I purchased my prepaid contract at the o2 Shop I was given a value which I would have to pay each month. I see that this month, my bill is 30euros more expensive than that value. I have checked the bill and see that my student discount was removed. I don't understand why this has happened if I am a student until March 2021. I have my student ID with validation for this new semester. I will not be paying this additional value as I uploaded my student proof when I was told to do so. I would like to be contacted by someone who can help me with this correction as I don't speak german.
Thanks a lot in advance.
