In January 2013, the defendant agreed with the plaintiff to provide them with three hair pieces. The plaintiff agreed to pay EUR 3.795 for this. The defendant's general conditions were applicable. The plaintiff's insurance company paid EUR 1.393 to the defendant; the plaintiff would pay the rest in installments. In March 2013, one of the hair pieces was delivered. In August 2013, the plaintiff's lawyer complained by letter to the defendant about the provided hair piece and the plaintiff did not pay the rest of the agreed installments. The defendant claims the rest of the purchase price and the plaintiff claims termination of the agreement and EURO 1.725,50. The first instance court granted the plaintiff's request, to which the defendant appealed.
