Tiana Bay review for MY ONLINE FASHION STORE

I had this app for 2 months, and it has a pretty good selection that frequently updates. However, customer service isn't great. I didn't know I had to register for on their website to process my order. That takes 48-72 hours, which is reasonable. I would assume that once an order is placed on Shopify it would sync into the app but it didn't for me. When I reached out to customer service, I sent 3 emails and made 2 phone calls. I heard back 2 days later. Again, I assumed that was because I did not read carefully but recently I had a customer return an item, and it took 48 hours to process the return and 48+ hours to receive the label. It's unacceptable. (I still haven't received the return label and had to eat the cost so it's not worth it) As a brand, customer service is so important so I'm torn. I think the lack of customer service is why I would personally not recommend this app.
