rude and rotten from the top down

On Friday 25 May 2018 at 18:00 i called the pizza hut at Zevenwacht mall branch and ordered the special pizza for collection, i was told over the phone that my order will take 30 mins. i then drove to collect it after work. I paid for my order when i arrived a little after 18:00 completely prepared to wait for my order. After a while i checked the time and noticed that it was 18:45 and my 30 min waiting time was exceeded. i then approached the cashier and asked her where my order was and she giggled and smirked and went about checking everywhere for my order. after about a few minutes she found my order in the re heater ovens which is located behind the cashiers till. she made no apologies and giggled while she passed me my pizza order. this made me furious as i felt i was due an apology for having to wait while my pizza was busy being re heated after been cooked completely. i then asked the cashier to speak to the manager and Ricardo the manager came from the pizza oven with a smirk on his face also giggling, when i saw this i lost it and demanded he compensate me for the poor service i had received. (i would also like to add at this time a number of customers walked in after me, ordered, paid for their pizza and left) the manager smiled and said to me its not his fault the person who took my order over the phone told me it would take 30 minutes for my order to be completed. He then smiled, so i asked for his name and advised him i will be reporting this incident to the head office. i logged a complaint on their Facebook page as well as on their website. On the 29 May i was contacted by a gentleman from pizza hut, who knew nothing about my complaint and had confused me with another's complaint, so I explained every thing from the beginning to him again and he said he will get back to me after speaking to the manager of the pizza hut(probably the same manager who was rude to me 4 days earlier.) On Thursday 31 May(6 days later) i messaged pizza hut on Facebook as i still had not heard or received a follow up call regarding this matter. i got feedback the following day Friday 1 June advising me they are in contact with the restaurant and will be in contact soon. A whole week later and no feedback and no one even knows the details of my complaint after i used numerous different platforms to advise pizza hut of my humiliation and dissatisfaction regarding their service. This is by far the worst service i have ever received from a fast food place and i will definitely not be going back to this store.
