I Pay Air
No updates, and the app is very buggy. It's a shame because they have no concurrence in Europe with their price.
The support is too slow to answer. Pushing the product may take 2 hours. It doesn't even send a confirmation, so you push it 5 times, and when you come back 2 hours after, you see 5 different products.
No update in 6 month, with all those bugs, and a support that is very slow to answer, it seems that Teezily Plus was just a brillant idea they are letting on stand-by.
