We encountered the problem of invalid clicks in Yandex.Direct and reached out to Botfaqtor. For three months, they promised that the solution to the problem would happen any day now, tomorrow or the day after. In the end, nothing changed: the ads never launched, and the balance just kept decreasing. Eventually, I asked for a refund of some of the funds that were automatically deducted, but I was refused. The response was that they had already worked off that money. Very strange and greedy unprofessionals. By the way, after them, the first random service started working, and now we are back in search and advertising!
