MarulaLab review for Trust Badges & Icons TrustMark

Tried the free trial, the app still charged me $39 even after downgrading the app. Contacted support, they told me they will refund, then no response. So I contacted Shopify and Shopify contacted the developer and they told me the fixed the bug (which they seem to do, but can't be quite sure again) and again promised they will refund, but no refund has issued since then and they no longer reply to emails. (20 days as of writing this). Recommendation: If you use the free tier, it's a good app - but don't upgrade because they will screw you over.
