Awign Internship - STIPEND NOT RECEIVED

I worked for Oyo Internship from **th July to **th August and then after completing. My project manager told me that ki nahi milega stipend and others ko mil chuka hai jinhone kiya tha oyo waale main.
All I did was ki ek audit main uske audit waale form main sign nahi kiya tha manager ne kyunki wo available nahi tha to maine use bola tha ki chalo theek hai Sirf sign krke send kr dena mujhe photo letter ki . Ab usme main khade thodi rehta uske Paas.
Kyunki manager told me ki owner will come after *hrs
Tabhi maine puri details fill krke ek photo le li thi And Baad main unhe bola tha ki photo dena mujhe Record ke liye
To ye jab maine debasmita mam(project manager) ko bataya to unhone bola ki kuch stipend se cut hoga Tumhaare
Maine bola theek hai cut kr lena Aisa hai to
And abhi ye bhaiya bolre hai ki kaise expect kr sakte ho stipend

Now you only think ki agar aap **-** din kahin pe kaam kro mehnat krke aur wo Baad main bolde ki stipend expect mat kro apniTum
To kaisa lagega aapko?
I have called them *** number of times and also messaged them on whatsapp but they all just see the msg and ignore it.
And ab bhaiya mujhe bolte hai ki tumhaare college ki placement and training waale se Baat krta hoon iske baare main. To usme bhi maine unhe bola krlo
Tell me what to do?
