The defendant asserted that the above price of supplied goods and additional construction costs were fully paid, and according to the whole purport of the statement and argument in the evidence Nos. 1-1 and 2-2, it can be acknowledged that the plaintiff prepared and delivered a complete receipt to the defendant on July 20, 2014 that the plaintiff was fully paid the balance of the supply price of the above waste boiler and the construction cost of the platform and the construction cost of the platform set up and delivered to the defendant. Thus, the above argument by the defendant is with merit.
