McDonald's shalcross worst customer service. Manager is pathetic no sympathy and emphathy or customer service s****s

Placed an order online for delivery at 11:30am money taken out and its now 1:00pm shalcross McDonald's then calls me up to say the order is delayed more than one hour delayed. Then says they will compensate me with a Mcflurry, requested a refund as the order was placed for my baby who is 2 years old. After requesting a refund said they will contact me after 5 minutes went more than 15 minutes and no call arrived then called them back and i was told i will receive a call in a very rude manner. While speaking to the store assistants i got hung up on more than 4 times. I then requested the area managers number which they have refused to had out and got told a refund will be processed which never arrive yet. Im utterly disgusted with the service i received and i wonder how staff are trained and employed. McDonald's been such a big and reputable brand to not carry out good standards is pathetic. Does it really take more than 1:45 to make burgers and nuggets and then get treated like **** from staff.
