We collaborated for about two years. They suddenly raised the rates almost tenfold, and did not warn us in advance. When we reached out, they responded very aggressively: "It's your fault, you should have read the news on the website." As a result, we ended up with many dissatisfied and uninformed clients. This is no way to conduct business; we have already found a cheaper and higher-quality alternative. Overall, they have become too complacent.
