  • image de Jan Michael S. ispConfig Server Problems/Solving €50.00 EUR

    “He got the Project on Friday evening. At the beginning all was looking very well and it seams that he is a nice guy. We informed him, that we are not going to make weekend. On Sundays I was checking my messages and I got a message from him where he was very angry, that we not accept his milestone request. he told as that he has removed all his work. this was 48 hours after the project was starting. we was wondering and I tried to contact him, but he was not answering anymore. then he wanted to get 5 euros from us because of the project fees. I do think it is normal that most of the people don't work on the weekend, and people can already wait until a Monday. Plus he got our cell phone numbers, if it was that urgent he could also call us and ask for the payment.”
