I did great with my teacher, until I get problem with app, that is not working, many complains against it, but Milena, that is only support always answering all emails, constantly tried to blame us, users, because app only can work if: battery constantly 100%, Internet speed min 10Mbps, a lot of memory and ALL other apps closed. I never saw app that need so many requirement especially 100% battery. I said this in my email: '

'Good day,

I closed all apps, I have 28GB free memory on my phone, internet speed approx 6Mbps and your app doesn't work!

Option one fix it send to your development pictures I'm sending now.
Second remove your nonfunctional app
Best regards,
Jelena

This was response from support name Milena (there is only her, no one else, when I wanted to complain against her she replayed on my mails, apparently company has only one employee):

Hi Jelena,

Thank you for contacting Verbling support!

Please note that the minimum requirement for internet speed is 10Mbps. Your device also must be fully charged. We recommend having lessons from the computer, if possible, for better connection.

I also would like to remind you that at Verbling we keep our community healthy and happy. This includes communication between students, teachers, and Verbling employees. Here in support, we're always at your disposal for any help and assistance. And we expect polite communication from your side too.

Please let me know if I can help with anything else.
Sincerely,

Milena
Customer Satisfaction Support''

I don't know what that means: 'we keep our community healthy and happy'! Does this sound professional and appropriate answer when you struggle to use app that you really need. They never apologies for bad app. When they refund they took money for class I didn't do, they canceled it, plus they kept fee they are charging. They didn't do any support, and not even saying something like 'Sorry for experiencing trouble with app, we are constantly working to improve. NO, just arrogant behavior, blaming users - you are costumer you are paying their salary but you can't tell them product is not working, you have to have all of this to work. What kind of app needs 100% battery to work? How they are not embarrassing to say that? Does anyone know is this joke.

I never spoke with such an unprofessional person who was telling me about happiness and health of community (what community?) instead of fixing app problem.

I now regret for not checking all this bad review about them. This kind of company should get serious fines for scams and lying about having app. I knew I will be busy and payed second 10 lessons in order to use them on my phone. I didn't received support, I was insulted by saying I wasn't polite, and then they said on Google store they blocked me for insulting community. One person, Milena, made all the problem for everyone, company refund, me losing teacher, teacher losing money. Such said thing, how one unprofessional entitled person can make so much damages.

There is no way of contacting them directly NEVER a good sign
