Bad treatment

The service at Nandos welkom was very bad after I paid a huge bill of over R3000 and a tip of R500 we were badly treated the lights were switched off while I and my family and friends were having our meals and drinks which was very rude and I'd judge that as poor service and wouldn't recomend or even eat at a Nandos ever again I want to put it out there that Nandos is not a place to be I'm sadend to say that I'm not happy and never will be I'd appreciate it if action could be taken seriously if not ill take a step further. Such behavior should never be tolerated as a business owner I'm disappointed at how employees handle businesses Nandos welkom will be in shambles if no action is taken and I will make sure action is taken as I spend a large amount of money.
