Pathetic service from Macdonalds ZA

Terrible experience from both the customer care agent and store. I placed an order at Macdonalds wonderpark, I received a call that evening informing me that the delivery cannot be made as they do not operate at those hours. Since I received that call I have been receiving calls from this macdondals every other day some days I would answer and other days I just left it to ring. On the days that I have answered I would just hear background noise or somebody would speak to me in a language that I don't understand and hang up. I got tired and reported this matter to an agent by the name of lelo at the Macdonalds customer care she then got someone from wonderpark Macdonalds to call me back after I sent them receipts of my call log the manager Sarah informed me that they don't have any history of these calls that were made to me. I felt like my complaint was not addressed and called Lelo at the Macdonalds customer care back she was very rude, told me I can't speak to anybody else but her because she is the only one working at the customer care. She told me I can wait another day to see if I'll be harrassed again and there is nothing else she can do. I am extremely disheartened by this treatment and service I have received, I had no idea this is how Macdonalds treats their customers.
