Left company within bond period

Hi, I have been working at a software company in Ahmedabad for the last 7 months, they had a bond of 12months. They kept two PDCs from me with the amount of 2 month's salary, if I leave the company within the bond period, they will deposit those PDCs. Now, after entering the company, and working for 1 month, I was surprised and shocked to see, that the company uses fack accounts and fake identities to generate business leads. Also, the technologies they have mentioned in the website they work, 60% of those technologies they have no single expertise. Some of the clients, which I used using the fake identity and not disclosing my real identity too, had not their works delivered. Moreover, they used to schedule hectic timings outside of the general schedule, and asked to work overtime for free. Now, after working till 7th of June, I came back to my hometown in Kolkata with lots of backpain, and headaches. I went to a doctor, and the doctor advised me to UNFIT FOR WORK for 1 month, and UNFIT FOR WORK OUTSIDE HOMETOWN for 4 months. Yet I was in therapies, and was planning to go back to Ahmedabad. Now, during the salary period, the salary for my 7 days working on June month, wasn't paid, and wasn't intimated that it will be not paid.I thought the company had broken all ties with me. Now, once I got a bit fit, I had a contact initiated with a client based in Kenya, who used to know me as the fake identity person that was used in the earlier company. But I revealed my original name, and clarified why I didnt provide my real name earlier due to company policies, and also said that I left the earlier company. Now, the earlier company is claiming that I had used their contact to generate personal business, where as the client never turned to a potential client due to fund issues from the client for 2 projects. Now, both the client and the company are behind me and harassing me.
