Missing units in lay bye

Good afternoon I went to ackermans in n1city goodwood to go pay my lay bye and take it out just to discover that he is not even comparing the merchandise in the bag to the slip to the check if everything is there.... Then I discover that the rest of my items is not there and the guy said it could be some where because they had a stock take... My lay bye was not eventually behind and I won't get the same items again coz I check and it's our of stock my daughter and son is leaving on Thursday to vredendal and I can't even give them there clothes that I did lay bye I am very Un happy with the service at n1city and its not the first time my experience in that store is bad some of the staff does not even have customer service knowledge they go on abd talk loud if i don't get my items before Wednesday I want all my money back and not a gift cards because it's not my problem that my stuff got missing and I want my full refund and will go purchase at another retail company and I even have an account with them pay it off and close it because I'm very unhappy
