The app is okay and the pricing is okay. This is what the one star is for. The overall customer support is an unbelievable shame: zero emails are being answered, no one ever takes the phone (why do you even show your hotline? +55 (21) 2147-4379 / 2147-4378 are both NOT working, because no one wants to be working there probably.) Also the chat function is useless, as noone is qualified enough to even receive a payment. Try writing or calling yourself and decide to not do any business with this super bad company.
