Write Solution of a given scenario-based question from contract!!

Brad always had a weekly Lotto ticket. One Saturday his numbers came up and he claimed that he had won a prize. The defendants refused to pay him, claiming that they had never received his coupon. Brad claimed that a binding contract existed between himself and the defendant. The defendant relied on the following clause in the Lotto coupon: It is a basic condition of the sending in and acceptance of this coupon that it is intended and agreed that the conduct of Lotto and everything done in connection therewith and all arrangements relating thereto (whether mentioned in these rules or to be implied) and this coupon and any agreement transaction entered into or payment made by or under it shall not be attended by or give rise to any legal relationship, rights, duties or consequences whatsoever or be legally enforceable or the subject of litigation, but all such arrangements, agreements and transactions are binding in honour only. Do you think Brad will be successful in claiming his winnings?
