Doesnt work and unresponsive company

I downloaded this app for my business for free, looked great and there was a feature that if I purchased the "ultimate" package in the inventory app and the invoicing app for an overall total of approximately $20 that I would be able to link both through iCloud and inventory would be able to be transferred directly into the invoicing app from the inventory app so you didnt have to re-enter everything and could easily invoice your customers. Sounds great right? Wrong. I purchased both ultimate packages, backed them up to iCloud and it didnt work like they claimed. I emailed them for help and got a couple responses of instructions on how it is done, and I followed them exactly, but they became unresponsive when I told them it didnt work. I asked for my money back due to their false claims, and nothing. They have terrible customer service, false advertisement and overall are thieves for keeping my money when their apps dont work the way they lead people to believe. I would NEVER give any of their apps another penny again. I hope this review saves someone else the money that I lost.
P.S. - I gave them many chances to correct their issues before writing this review, and they made their own choice to ignore me.
Sincerely,
One angry customer, you know who I am.
