Scammers – Navionics® Boating Review

I paid $14.99 in Feb on iTunes for a one year subscription. I used it three times ice fishing and liked it. Now the app does not work and tells me to upgrade to Navionics+ for $21.99 year. This current app says I no longer have a subscription even though I paid for it on my credit card. I reached out to their bell desk and their auto-reply said that due to high volume they might not get back to me for days.
