I can't say anything bad, it's just that the collaboration didn't work out. I set up all the campaigns, showed results for the first 200 UAH, and then the client didn't top up the advertising account. When I asked why she wasn't topping up the advertising account, she replied that she didn't know that you had to pay money for advertising on FB, she thought that paying you for the work was enough... In this case, it opened a safe on the exchange. Then we just sat for a month, waiting for the project deadline to end, and then it was closed...
