Poor Service - Cannot Fulfil Order

I placed an order on the 14th of December 2021 for delivery only to get called on the 16th to say no stock. What is the point of placing orders online if Dischem will not fulfil the order?? Why was I allowed to pay and proceed with the order if there is no stock? Dischem did not even attempt to try to fulfil my order. False advertising. Do not buy online from Dischem.
