Poor customer service

Had my 1st experience with a missing item , I just requested to receive the item via delivery as it was for kids and one was missing ,I did not in any way request anything free nor did I requested anything extra. For my inconvenience I received a coupon to the value of the amount of the missing item at R24 , I quried the fact that I still had to pay delivery and minimum spend on the app does not allow me to do so . I was told that that's all the compensation I would get and the delivery would be paid for . How does one check out with a minimum spend not met , 🤔
