There is a breach of contract if they had made these promises.
They will not be able to enforce recovery of bond money since they have give you no training or adhered to their words while employing you.
They have misrepresented the nature of the job.(From what you are saying)
You can give notice and leave the organisation.
They can avoid giving you a relieving letter, but they cannot stop your PF.I am sure you must be knowing your PF A/c number and probably having PF statement.
You can think in terms of continuing the same PF a/c when you join some other company.
Arrange a meeting with your HR. discuss all above points & your greviences. Indicate your disappointment & efforts taken to stay with the organisation. But also indicate your intentions/fredom to leave if the promisesare not fulfilled.
Indicate non-provision of trainings & clear that the bond is only an mutual agreement between you two parties & holds no value in terms of local laws. If compnay does not respect their terms, then there will not exist any further mutual agreement.
Prepare the detailed minutes for this meeting as you discuss, & circulate the copy of it to HR & your immediate management formally (Through e-mail).
Ask the HR to sign it & send back. If they refuse you can escalate this to higher management, & still use this unsigned copy for further reference of the discussion. If HR denies for your minutes, then they would be obliged to provide their copy of minutes for your record.
Do your actions intentionally & calmly. Do not give company a chance to take disclipinery action against you in terms of termination.
If this does not work, then labour courts are there to take matters further, as suggested by other experienced menbers above.
