Postship Order Tracking Upsell

i downloaded this app 1 month, i did not delete it yet because i didn't have time to set up a new tracking app yet, horrible service, they take 5 days to response back, never solve a single problem from your request, i had multiple times i can't count that i wanted to get help. THey said yeah will look into it, never never, multiple times like that. i even said, i don't subscribe the paid plan yet not because i plan to use the free one, but i want to see their service and how the app worth. OH ITS NOT FREE.
