PECRON review for Omnisend Email Marketing & SMS

This APP is like a scam! It provides online support for the first few days when I install this app, but this function has disappeared suddenly and no way I can find it now. I paid the basic plan $30 which is apparently higher than what it is advertised here $19. Now the money has been taken from my account but it still shows I'm in the FREE plan. When I click upgrade my plan it directs me to a page that I can see the subscription fee of $40 for the basic plan!!! This is definately unethical
