Jai paid RM1000.00 to Mat as a deposit to buy Mat's Axia car which cost RM 15000.00. However, Mat has asked for another RM1090.00 because Abu is also interested in buying the car at a higher price. According to Mat, if Jai refuses to pay the extra money, Mat will cancel the booking, confiscate the deposit money, and will sell the car to Abu. Meanwhile, Mat's wife Mala is the owner of the Rsa-rsa Ceria cake and bread shop. On September 30th, Mala sold her business to Manja. Manja stated that she intends to continue the cake business and also uses the same name, Rsa-rsa Ceria. Two weeks later, Mala's good friend, Rusla had ordered cakes and bread from Rsa-rsa Ceria for her son's birthday party for RM 300.00. Rusla has also paid a deposit of RM100.00. Two days later, Rusla finds out that Rsa-rsa Ceria has been sold to Manja. Rusla wants to cancel the order. In another incident, Haroom Company in U state had entered a contract with Pattaya Company in JJ's country to sell harum manis mangoes. This sale is in violation of the law in the U state which bans the export of harum manis mangoes out of the country. The lorry carrying the harum manis mangoes was detained by customs during shipment to JJ's country. As a result of the failure of Haroom Company to supply the mangoes, Pattaya Company intends to sue for damages. Advise Jai, Rusla and Haroom Company.
