Really disgusted with the ITC Parel!

Really disgusted with the ITC Parel!
1 year back on this day did a professional photo shoot for ITC Parel.
They wanted a creative cover for their food items and basic facilities that they provide.
I am a small-time but professional photographer. When they contacted me one year back, I was more than happy to do the job in their quoted price.
I dedicated my entire two days (7 and 8 hours shift) for this shoot.
Upon completion of the job I asked for my honest remuneration. They stretched it to a later date. When I asked again later, they stretched it even further and they did it again and again.
It is almost a year and all I ask from ITC Parel is for my honest earned money.
I am uploading the screenshots of the conversation to prove the authenticity of my claims.
Guys be aware and boycott such organization.
Once again, I publicly ask to @ITC Parel to provide my remuneration asap.
