Poor interface, zero communication/support

Hoped the Pro version would allow me to easily add some features to maps created in Mapbox, but it really didn’t provide the functionality I was hoping for.
As a consequence, after giving the Pro version a go for about 20 minutes and realizing that it wasn’t going to provide the features that I needed, I requested a refund.
After repeated requests with no answer and no refund all I am left with is providing this review.
I wouldn’t recommend paying for this plugin, and given the lack of responsiveness to a customer, I would be very reluctant to put any faith in support from this company.
