Klaviyo: Email Marketing & SMS

I was urged by one of their Affiliates to add this to my Shopify. I Added it created my flows then they disabled my account. I do not owe money that I can see as there isn't anything showing it. I have not even used them to send an email....Do not support Fiverr people adding this app. I contacted support and they couldn't help. Spending a lot of money on an app that you can't use is a bad company investment
