Agreement to sale cancelled but refund cheque might bounce what to do

On 01 February 2017 A agreement to sell of apartment was made with the builder for total consideration of rs 40 lakhs and 25 lakhs were paid and rest rs 15 lakhs to be paid within six months . After one month the builder approached the party that the builder is getting a much higher price for the property from a third parry and hence the builder will give the party a amount of rs 30 lakhs to cancel the agreement and the builder paid a cheque of rs 30 lakhs and a cancellation of agreement was made after that the builder told the party not to present the cheque of rs 30 lakhs and grant him a further time of 2 months . After passing of 2 months the builder is asking for 15 days more . It seems that the builder is not ready to pay the amount and nor ready to hand the property and is trying to cheat . Can a criminal case can be filed against the builder. How should i proceed so that my amount 8s recovered ?
