An individual left a job after two years, paying a £1.5 lakh bond penalty. They claim their employer changed the salary increment cycle without notice, meaning they hadn't received a raise since April. They used their August salary to offset part of the bond payment. However, they later received their August salary in full and are now being asked to repay the excess amount. The advice given suggests consulting a local lawyer due to the complexities involving the bond, the alleged lack of increment, and the mistaken salary payment.
