Can’t get Pro version

I’ve been trying for several months now to get the Pro version, which has features that I need. I’ve left multiple messages on the purchase website, but have never received a response. This is unfortunate – if it wasn’t for this issue, I would give this a 5 star rating. The free version works very well for me, without difficulty (as long as it is the only plugin that uses the Google Maps API on the page), but I need the Pro features. Frustrating!
