I have given the work by the freelacer on 4 january-2021
they told to deposit the amount as a security purpose, so i did
within 2 days i was provided with work details.
i started to work, i sincerely completed all the work with in duration of time that they provided.
after submission of the work they even are not responding and after 2 days they are saying that my work is incomplete.
they even not ready to refund the amount and payment as well.
I just want my money back along with the payment for which i worked.
