OFFICE 365

Hi

I have just purchased via my Mac Book Office 365 on a 1 month trial with the intention to continue to use. I have been told my purchase is successful and have set up a Microsoft account.

My issue is I cannot seem to download the software. I have tried the App Store but that just repeats the purchase process,  there is no key to download with the purchase and I wonder can anyone tell mer and help on how to get software access? Thanks Allan M 2060
