Regarding job bond

I joined a company in October after interviewing for the position of an Amazon Marketplace Manager. During the interview process, I was clearly informed that I would be considered for this role. At the time of joining, the company required me to sign a one-year bond agreement. However, after joining, I was informed that I would instead be assigned to work on Zepto PPC (Pay-Per-Click advertising). I was told that if I faced I joined a company in October after interviewing for the position of an Amazon Marketplace Manager. During the interview process, I was clearly informed that I would be considered for this role. At the time of joining, the company required me to sign a one-year bond agreement. However, after joining, I was informed that I would instead be assigned to work on Zepto PPC (Pay-Per-Click advertising). I was told that if I faced difficulties or did not understand the work, I could inform them and they would shift me back to the Amazon role. I worked in the Zepto PPC role for one month and realized that this type of work was not suitable for me. I then informed the HR department and requested to be moved to the Amazon Marketplace role as originally promised. The HR asked me to try for one more month, assuring me that if I still faced difficulties, they would shift me to Amazon. This process continued from November to February, where every month I approached them with the same request to change my role, but each time I was asked to wait for another month. In February, when I expressed my intention to resign, they arranged an interview for an Amazon-related process. I also underwent one week of training for that role. However, just before the interview, I was informed that if I got selected, I would not be allowed to take more than two days of leave, and my bond period would be extended beyond October (effectively increasing the bond duration). Due to my health condition, I required approximately three months of leave, and therefore I was unable to proceed with that interview. After this, I requested that if there was no Amazon role available, I could be assigned to a Flipkart management role instead. However, I was again assigned to Flipkart PPC, despite clearly informing HR that I am not comfortable working in PPC roles and that I had already realized from my Zepto experience that this type of work is not suitable for me. Currently, my training period in Flipkart PPC has been completed, but I am unable to perform well in this role because it requires fast, self-driven learning, and I need concepts to be explained more than once to fully understand them. I am certain that I will not be able to meet their expectations in this role. At present, it is March, and I still have around six months remaining in my bond period (until October). The company has now stated that I must continue and perform in this role, and that they have already done enough for me and will not make any further changes. I feel completely stuck in this situation because: I am unable to perform in t
