    “wasted more than a months, he took my project and then he hardly worked on it, 1) i had to literally chase after him for the updates and then when he reply he says, he was working on other projects and didnt have a time so my question is if he dont have a time then why he took my project. 2) i dont think he ever understood my requirements, before taking and accepting a project, he said yes he understood and he will do it accordingly, but once he accepted the project, he wasnt able to do it and then started to say that, please mark this project as complete and we will do this functionalities in the next phase, so he decides what he will do and what he will not and not us, totally unprofessional. 3) i almost said 10 times to push the code on my git repo and he never did that and then started to say, i will only pay once you pay, i mean what in a earth he was upto? how you can pay for unfinished jobs? how i can see the quality of his code, whether he did himself or copy pasted it? Simply stay awayyyyyyyyyyy, totally time waster”
