Is my case firm to file a case against my previous employer

Hi Further to the comments mentioned above, you could send them a covering note and the cheque with your notice pay amount.

Dear Friend/s
1. RL is issued by every company after full & final settlement is calculated and finalised whether the employee has to pay or company has to pay.
2. If employee has to pay to the company then in that case RL is issued after the employee has made the payment to the company.
3. Hence the recovery notice of the company has no standing, it is misplaced.
4. Company can only claim when it admits an error of calculation has taken place hence the notice for recovery. In this case the company has nowhere mentioned that it was an error on the part of the company, on the other hand the company is blaming the employee for violation of contract of employment.
5. Companies cannot legally stop any one from taking up employment after leaving A company and joining the B company.
6. In my opinion employee should not pay a single penny to the company.
Warm Regards
