Editing of the Laravil site
I do not recommend cooperation! Be cautious! I think it’s a fake account. I came out to contact calling gave all the access, showed what and how to do, the person said that everything is clear what he begins to do, eventually I ask how to succeed? I understand the answer with TZ, the next day I ask if there is no answer clearly, the whole time of the project lasted the person doesn’t go out to contact, the calls in the telegram blocked, the SMS does not respond, the service constantly shine what happens to the SMS in the service does not respond. A week of time resulted in zero.
I close the project.
I do not highly recommend contacting such an irresponsible person.
