Terrible customer service

I went to nandos chatterton road in pmb durban i was on lunch and I'm pregnant I got there the queue was empty I was with my colleague we ordered 1/4 chicken,chips and a roll,magnum almond,and sweet corn I was number 171 on my slip then we waited the queue started to pile up with people sitting in as well as buying take aways then 15 minutes later they started calling numbers which they started from number 172 they called out the orders up to number 178 and we still sitting patiently waiting without anyone updating us or anything after waiting for abt an hour then I asked my colleague to go and find out what happenning as we have waited for so long when he got to the front nobody seemed to know abt our order the waiter ended up going to the chefs but they all looked confused there were two ladies who kept on looking at us and laughing then she said they are still looking into it then we waited the manager came and said they are waiting for sweetcorn without even apologising and that was over an hour of waiting when the order finally arrived I remembered that the last time I bought from there the meal had no sauces at all but had requested them then I checked my order and again there was no sauce in the meat which was also sooo dry and the roll that was stale.i made a decision that I will never set my foot in that nandos and I'm telling everyone about it.
