PayJustNow ****mer company unable to close account.

I've opened an account to purchase something I wanted but in the end I no longer needed it. Also after seeing how much "interest" to the payments that was added I was reluctant to pay the payments and rather save up the money instead of becoming a slave to credit. Now sitting with an unwanted credit facility I was trying to figure out how to close the account. There is not way to close it on the website or anywhere else, you need to email them. I've emailed them twice now and they won't respond. Meanwhile I get spammed (you can't opt out of these spam mail the buttons wont move) into my moer by their forced advertising! I tried their chat bot on their website that eventually says it will connect you to a person.... NOTHING. There is no one that will help you in the company. I WANT TO CLOSE DOWN MY ACCOUNT OR KNOW HOW TO TAKE LEGAL ACTION AGAINST THESE MOFO's!
