Disgusting Customer Service

Shocking Service ordered on whatsapp at 10h18 our order arrives at 11:28 with a missing cooldrink 2 hours later, I messaged to advise even sent a picture they advised would send but at 13h11 nothing arrived I explained its 2 hours later again I was told "Yes we are busy will send as soon as we can" I then respond saying this is shocking service since it was their mistake. I'm then told the driver gave me 2 bottles of coke. I then sent the picture again "500ml coke missing. My initial order was also wrong because I just ordered the burger with chips didn't ask for a cooldrink with it but since it came and you charged for it we took it." I'm still questioned at this stage "How many cold drinks did you get in total 3 or 4" I referred to the above picture and was just told "Okay sending now" No apology whatsoever about the mistake and how long we waited all in all. Terrible customer service I personally would never order anything from them. There is no e-mail address but their contact number is 0822165595.
