Great care! They are scammers and also rude! I registered in the trial version (in which you have to enter your credit card information) and two days later, seeing that this application was NOT WORKING (it has not found a SINGLE COMPETITOR) I requested to unsubscribe ( There is no way to do it yourself, there is no button for that). The person who helped me told me that if I didn't give him an explanation that he wouldn't cancel me (I gave it to him on the first day, this application doesn't work). They didn't cancel me and on the second day I told them that I don't have to give any other explanation that I wanted the cancellation at the moment, but they told me yes but they still haven't canceled it. Today is day 3 and I'm still registered, I guess they will be waiting for the trial period to pass and charge me for the subscription. This is a real shame, Shopify should make sure these things don't happen. PS: By the way, in 8 years that I have been on Shopify and with hundreds of tested applications I have NEVER given a bad review. This is de first time.
