Ratings and reviews

"I had a very poor experience with Kast. They claim to provide ACH/wire transfers to US accounts, but my transfer was rejected. When I contacted customer service, they had no information regarding the rejection, yet I was still charged fees for the failed transaction. Between the high transfer costs and the weak customer support, I cannot recommend this app. Be cautious of their claims regarding US transfers."

the 5% rewards is a trick. they will, in the future give you a crypto token. and you can't even sell it unless you take a huge knocke or sell it over two years. so be careful. I should have read the small print. there developer response is a clear indication of how much of a scam their 'rewards' are! still no sign of the promised 5% rewards. a scam!

scam application. even after the verification provided my transaction and account was blocked. clueless customer support as well.
