Lame online/delivery experience

If only one can give a 0-star review. I ordered 3 x trio sets of masks online on the 8th January 2021. On 22 January I finally received an email to say that my order is on the way. Yesterday, 25 January only 1 x set of masks arrived via courier. I enquired with their head office as to where the rest of my order was. I only received an email stating that they no longer have stock of the other two sets of masks and get an SMS with a refund. While I am thankful that the money was returned, I wanted the masks. Super slow service in a time where people rely on online/delivery services, with shocking customer service. I am sure they noticed that only one set of masks was in the packet to be delivered and they still did not pick up the phone to speak to the customer. What a lame excuse for an online experience.
