Nando’s Im disappointed

I am writing to express my disappointment with the service I received at Nando's Kingsburgh today at approximately 12:00 PM. I had purchased my favorite drink, "Tropical Sunset," but upon leaving the store and returning to my car, I realized that the lemon and mint leaves were missing. I returned to Nando's to inform them of the missing ingredients, and I was told that they had run out of both lemon and mint leaves. They offered to go to a nearby grocery store, Pick n Pay, to purchase these ingredients. I patiently waited for almost 20 minutes, but when they returned, they only had lemon and not mint leaves. They then asked me to leave the store without providing a resolution to the issue. I am extremely disappointed with the service I received at Nando's. It is unacceptable to sell a product that is not complete, and I expect a higher level of customer service. I hope that this issue will be addressed and that steps will be taken to prevent similar incidents in the future.
