WASTE OF MONEY

Horrible!!!!! downloaded on my phone and my daughters tablet. Bombarded with ads so subscribed to premium to be ad free. Then spent more money to get credits/minutes but every time I tried calling anyone it would only ring for half a second pop an ad or just say call failed. No amount of money helps make
Calls go thru and no way to get a refund or dispute through the app or App Store. No customer service phone number. Now stuck having to dispute with my bank!

Difficult to use

Incredibly confusing ads, pricing scheme is complex and not straightforward. I just want to make a call.

Not worth it

Nobody wants to watch ads and spin wheels to call people, it’s really annoying and takes up too much time.
