    “Actually I lost my money with this freelancer, you can check the chat conversations. I hurried and released the money without corroborating the work and I feel that he scammed me. The problem was: I had an application in IONIC which I tried on some occasions and generated the test apk. After a while I could not generate the apk and so I looked for a freelancer to help me with that. The freelancer I hired worked and generated the apk, as it did ?, I have no idea. But I imagine that he deleted, added, modified things, that allowed him to generate the apk, but in turn that apk does nothing on my phone, I can't even login. Why did I release the payment? Because when I generated the apk, the server was down and I could not prove, so I assumed that was why. When I raised the server the problem remained the same, I could not login. To get out of doubt, I deleted that apk and installed the previous one and that if I can enter. I kept discarding options and got another phone to try and the problem persists. The freelancer tells me: "I did your job, generate the apk", but at what cost?, That the project does not do what it did. In any case, I know that I will not recover my money, but I write, because the truth was a very bad experience, working with him and in the end, I did not get the results.”
