WWICS Group — Work visa

I had given my work visa to wwics Ahmadabad branch with 5000 $ advance . after some time they closed their Ahmadabad branch office and know me my file is now at mohali head branch office . i had complained for transfer my file that time they told me if i not want to continue my file they treat my file as voluntary withdraw and will not return my advance money . due to this reason i was forcefully ready to continue my file . but after this my file was stuck their for long time after my main mails they just reply and told me they will do my visa as soon as, after my trail of mail they tell me you are getting only 14 $ wages which was very less as committed by their Ahmadabad branch
and if i am not ready with this wages they nothing do for me and will treat my file as voluntary withdraw and will not back my advance money, i need help for get back my advance money or my work visa
