A have a license awkward

The selection procedure for my university was not understandable for me.
There are too many entries and depending on writing even different choices.
After several attempts I came to enter the email address. This was rejected by Microsoft, although this was true. There was nothing to be done.
Ultimately, I have to turn to the paid Hotline. This has me then helped very friendly, although the procedure here was not easy and the ladies with German words and umlauts such had their difficulties. We have it but managed to get the added code to log into the program, and then again for activation.
If Microsoft ever wants to catch the students and ensure that they continue to use later Office and not something else, then it should be applied here more accommodating! Complicated and nerve-wracking is hardly possible. In the age of Apps inconceivable but I had already paid the amount and could not get it back.
Now hope that the version holds least what Microsoft has promised in the advertising.
