No access to my Word documents because spelling error in name for product key

I didnot install office on my laptop. It had come with preinstalled office 365 apps.
I received the purchase confirmation from lenovo germany on my gmail id (which is actually from India)
I have actually used the student discount while purchaseing the laptop using my university email id to get discount and while billing I gave my indian gmail id.
I am using the same indian gmail id for logging in to my microsoft account for activating the office on my laptop. I also tried asking for help on lenovo support but they say to ask microsoft support to give product key or activation help. I also asked microsoft but I get no response.

Hi Dave,
<br />Thanks
<br />But what if I need such a large number for calculations, the one with the ´ is no longer a number?
<br />If you do not know why this is the case, it is not a drag because I do not need a calculation for my current case.
<br />Is just to expand my knowledge.
<br />Sincerely, Felix
<br />

Sorry but it would be really helpful if the description of the problem were read properly. It is precisely because it is not possible to do this that I posted here in the first place. When I try to do anything with that account it refuses to let me in and gives the error message that the account name does not exist. It does. Microsoft created it. I have no access to it, that is the problem.

Hello Raymond,
Thankyou so much for the response.
I purchased the Microsoft 365 single (1 year subscription) directly from lenovo germany offcial website along with my laptop.
I do not get any error, but I am asked to add product key or purchase again a subscription .
Looking forward for the help.
Thanks and Best regards
