Microsoft does not care about its paying subscription customers

My credit card for my MS Office subscription had expired. I supp**** the data for the new card and it was accepted. Within a day or so I received a message that the transaction could not be processed with no error or problem indication. I use that card on a daily basis with no issues. I repeated the process 3 times, each time the card was initially accepted and later rejected. The different information pieces shown on the MS system are at times contradictory. My core complaint is that there is NO OPTION to email or otherwise contact anybody at MS to resolve the issue. This shows the contempt and utter disregard Microsoft has for its paying customers. I will in future avoid doing business with any company that displays such behaviour. As it stands, my companies used to be big supporters of MS products and services; that has been reduced by about 90% during the last few years and given the described behaviour, I don't see that changing.
