They don't respond to customers.
At first, before paying for the course, they were accommodating. Then they sent a contract with a past date. I tried in every possible way to contact them via e-mail, by phone, through social networks, but they absolutely did not answer anywhere. After that, I decided not to contact them and with great difficulty got my money back. If they could communicate normally with their clients, at least respond to them, then I would learn from them.
