Not Off To A Great Start!

I just paid $5.79 (CAN), in the Canada iTunes App Store on February 8th, 2016, hopefully looking for a newer, better, Shipment Tracking App since the "Posted" tracking App went all to Hell and doesnt work at all anymore & hasnt for quite some time now. I thought Id give this one a shot. I saw both reviews for this (friends of the Developer perhaps?), which were 5/5 Stars. Im expecting a package delivery from Purolator Courier which will be delivered today, (as per the info on a free Tracking App that I use, and the Purolator Courier App), as well as Amazon.ca Item Tracking. When I put the shipping info into this App, all it ever says is that "Shipment Information Pending", and doesnt show the few tracking stops (and starts), and/or the times, in different city hubs on its way to me. You cannot click on the titled field that youre Tracking to Edit it, or just to see if all of the info youve entered is correct. This App is NOT off to a great start and this isnt a cheap App! Ive sent an email to the Developer, and I hope this gets fixed (in which Ill change my rating, but only after several shipments using different shippers from around the globe), to see if this problem persists. As it stands now, I wouldnt recommend this App.
EDIT: After contacting the developer trying to get things straightened out, & him getting flustered, this is an example of the kind of response I get via email because he didnt like my review:
"3. Switch up the usernames. Don’t leave a review on my app with the same username you used to sign up on a penis enlargement website with. I also found it interesting that you have 67 pages worth of reviews in the iTunes store, you also have quite a bit left through your Facebook page. You bored??

Warmest Regards,
NICHOLAS"
