Help - a bit confused here.

I pay for my Outlook (formerly Hotmail) e-mail account by direct debit

Last month I received confirmation that my subscription had been renewed. However, yesterday, I received an e-mail saying that my subscription had been cancelled. On further investigation I found that the payment had been declined and there is no obvious reason for this (plenty of funds in account etc ...)

I need to get this resolved but there doesn't appear to be a way of doing so.

Following the advice given  - i.e.

To reach Customer Support, go to https://commerce.microsoft.com, select 'help', click 'Getting help' and then click 'Contact Customer Support'.

..... does not give me the opportunity to progress this other than posting this question on the forum

This is VERY frustrating .... is there any way in which I can resolve this ?

I am a UK based user
