AClone: Backup & Duplicate

Bought a theme (electro x) from them at the start it had some bugs but they have been super helpful with everything, they have worked on fixing several bugs and did a lot of other stuff I asked for, would highly recommend going with these people! great team and customer service.

The app doesn't work, is impossible to make a full backup. You always get a different error.
When you contact customer support asking for a refund or help, they don't respond, UNTIL you leave a review. When they see the review automatically contact you, extorting you, saying that will refund if you change the review. In my case, because I didn't do it, they don't respond anymore. Be careful, already file a claim with shopify.

ArenaCommerce is my ultimate Shopify solution. Their skilled team knows the ropes, making my store awesome. Quick fixes or big changes, they nail it. The 24/7 support is a winner, showing they care. With ArenaCommerce, my online shop rocks!

I tried this app twice.
The first time, couldn't do the backup because always got a code error, and had to contact customer support. After a while they fixed it. But didn't convince me to pay every month $60 for something that doesn't work properly.
After a few months, I tried again, paid again, and the same, when I try to export the site, I get an error code saying that I need to contact support. Even when I try to import the theme in the other website, I get errors too.
I contacted them asking for a refund or solution and they never responded.
Will file a claim with Shopify.
Update: after a week, Shopify's customer service involved, got a response and they refunded the money.

The product works reasonably well. But, the support is non-existent. I signed-up for their most expensive plan and have submitted a couple of inquiries but have not received a response. I will modify this review if I'm able to receive support.
