This is it

### 1/5 — WASTE OF MONEY

*2025-04-29*

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!
