Bad service at Macdonalds Grey Owl

I was at Macdonalds Grey owl in samrand... They gave me a wrong order after waiting for so long then I decided to add juice on the wrong order they gave me again I had to wait long before they can give me the juice I decided to then leave without the order they also told me they can't refund me... So basically I went there to give them my money since I did not get the food I initially wanted so my money went down the drain
