IBM India — provided incorrect information in the document

Hi,
I was hired by ibm india pvt ltd on 25th january, 2019 for the position senior systems engineer. They had promised a project and work location which they did not adhere to after i joined. As i could not continue in that project and since ibm could not provide me another one, i decided to resign. I left the company on 25th march, 2019. When i received my position in it different and which i was unaware of. On being asked to correct it, they did not take any action. They have made this change without prior information.
