Why is the law not very strict in imprisoning accused when judgement passed in favour of complainant

Dear sir/ma'am, We had filed a cheque bounce case against the accused and after two and a half years of wait time, after three judges changed in the meanwhile the judgement was passed on Jun 2019 that the accused has to either return our money or to be imprisoned for 6 months. While we were thinking that it's the end of our struggle, it was shocking to see that she's approached the next court by paying a minimal deposit and now it's over one and half years that neither she nor her lawyer are appearing to the next court. All that we get to hear from our lawyer is the next hearing date. Having faith in the legal system, we're fighting for our justice however the opponent's lawyer is finding all the options in the law to buy more time for accused and prolonging the case. With all the stress we've undergone, we're left with no options inspite of having all the evidences against the accused. Is it advisable to take a second opinion on this or is this how our standard Indian law system is designed?
