Terrible delivery and customer service!!

I ordered a delivery from Steers Plattekloof through their app and it was confirmed at 9h05. I thought fir a store 5minutes away 40minutes would be sufficient time to prepare a burger and chips and delivery. At 9h39 I was called by Steers Plattekloof and the order was not even made yet!! Furious at this news I cancelled my order. Just before 11 I got a call from the driver - he is outside with my food... I was livid, but gave him a tip and paid my R177 bill... not to mention my lemon twist was swopped to a sprite without my concent and my fanta was left out completely AND my food was ice cold!! I had to call the store twice to finally get my Fanta delivered before 1pm... my hard egg was soft and runny (I dont eat yolk at all and everything was covered in egg yolk and my chicken patties were burned and tasted bitter and were nit hot as I requested either!!) I complained on the steers page and sent my contact details as they requested... after 6pm upon asking them what is going on with my complaint I was told via Facebook they have handed over my query to their team... an entire day and they could not even phone me after my whole ordeal. I am appalled at their lack of customer service and just respect. Even when I was called by Steers Plattekloof I was blatantly **** to stating that they only received my order at 9h25 after I had received the confirmation at 9h05. This is a joke and a poor excuse for a SA company. Pathetic I want this to be rectified and quite frankly I want my money back and a decent apology for this mess. I am furious to say the least.
