Mcdonalds Old Fort - Pathetic Service

Purchased 6 doughnuts from the branch at Old Fort Road, Durban. Got home and they were rock hard. Every time I try to call the store number, no one answers, so I didn't even bother to waste my time and try. Went to return it the following day, and the staff and manager refused to believe it was purchased stale. They say that maybe it got stale overnight since I brought it back the next day. Do they expect me to do a freshness test of their food items the minute I get into my uber ? ****** ridiculous. Disappointed as im a regular at their establishment.
