Great Costumer service, they make some changes i want for nothing and in few hours. Excelente servicio al cliente, les pedi unos cambios y lo hicieron en menos de 1 día.

— Tornillo De Cran

Terrible App - Loyalty program doesn't work. So many frustrated customers spent months saving points only for them to disappear when they try and spend them. AVOID.

— Zombie Vapes

Although the app is functional, it also loads a malicious, obfuscated Javascript file that looks for competing apps and where detected it unloads their scripts, breaking their functionality. When I flagged this to the Treedify team, I was curtly and disingenuously told that it "needs to check other apps to prevent potential conflicts to make the app work normally". There is no legitimate excuse fo...

I tried to cancel my subscription before the trial but there is no way of doing it in their app that's why i give it 1 star. I should always should have this option available, ridiculous.

— WHiSP Products

I keep being charged for an app that don't have. I talked to someone last month and got my issue resolved but I am still being charge for an app I don't use or have been deleted I want my refund please.

— Liyah's Goddess Shop

Customer service is beyond the worst, I have an Automatic discount with Shopify and when It comes with Automatic discounts it doesn't work with selly ask selly any advice. They just reply my ticket link

I liked the layout, but the app did not sync with my store. It also changed the dates on which the discount should be applied.

— Namibian Biltong

Worst customer support ever! not worth the money, instead of fixing their app script the support ask me to delete the other apps because causing conflict with their apps, even though their script who causing an error on my site.
