Microsoftonline jobs

Hi there, I have recently started a small business called Turquoise Port and registered the domain through Crazydomains. I managed to set up my emails with @ (MS365), but now having issues setting up my website via Wordpress because I can't use the DNS as it has already been used for microsoftonline. I was told by Crazydomains to use the A records, but that does not seem to work... Please see screenshot of chat with Crazydomains attached.
