Lack of assistance for an expensive app

Purchased app years ago. When they changed their policy from allowing you to have the app on 3 devices to 2 I hit a sang. No notification regarding this change. Well I have hit a snag again. They have probably changed the policy to 1 device. I would not know as no notification once again. Whereas the previous snag was sorted by Guy Gibbon quickly, this time emails have been ignored. I have emailed both him and the sabirding help. Nothing. I think that an app costing R500 should always have assistance available, They did away with phone assistance and now you are left high and dry. Not worth the hassle at the end of the day but as I did purchase the app at least 10 years ago I should still be entitled to some help. The app itself is brilliant.
