How can I contact support chat and stop domain name renewal?

How i contact support chat ??

while i click the support chat it asks my store name i choose my store and then nothing, redirected to the main support page..

Another thing i have a store i made a year ago i made it ‘paused’, got email saying it gonna renew the domain name more 2 weeks, how do i stop it?
I can’t get in the store, if i get in, new charges to apps will apply
