Hello,
Are you sure it is the MS 365 Basic subscription that you have? The Basic subscription doesn't include Office apps, like Word, Excel, Powerpoint, etc. It is only for 100GB of OneDrive storage. It is explained here: https://support.microsoft.com/en-us/account-bil...
However, you can always use the web version for free, and that's via https://www.office.com
To verify what subscription you have, you can go to https://account.live.com > Service and subscription.
