Development of a CRM system for managing automatic sales bots in TG

I paid for the second stage, and as a result, nothing was done for 30 days. The project was not completed. I lost time and money. My advice is if you choose this contractor, agree on the full amount right away and have all the work under one stage. If they try to persuade you to break it down into stages, you will be scammed and they will disappear after the first payment.
