Subscription for Microsoft 365 Family charged twice.

Hi currently I had a free try one for the Microsoft 365 on your App Store which I agreed to convert to a one year paid subscription. I have been billed for two subscriptions of £79.99 each and my apps account is showing two subscriptions (one with a word Logo and one with an Excel logo) . I rang the help desk at Apple and was informed that the charges related to separate charges for word & excel. On checking the details however the version I have includes word ,Excel ,power point ,one Note and outlook as standard . How could I have been charged twice for the same subscription. I have gone through my subscriptions panel to try to cancel one of the subscriptions and obtain a refund but Apple state that this does not qualify for a refund. This cannot be right. Can anyone assist?
