Game pass ultimate refund

Hi, a few months ago I purchased game pass for £1 and stated that I did not want recurring billing however yesterday I noticed in my bank account that I had been charged £32.99 for 3 months of game pass ultimate that I absolutely did not want. The support
system has proven to be useless - virtual support has sent me in circles with no actual way to request a refund as my payment is not showing up on the “request a refund” page at the moment. It also says on the support page that they have a phone line currently
open but I cannot actually find a way to get this number as when I put the category of my issue in I get sent to the same useless support pages. It feels as if microsoft are making it as difficult as possible for me to request a refund which is very difficult
as with the current global situation I need every penny for necessities. Any help would be appreciated - thanks.
