Pathetic Service - Lazy / Untrained Staff - Please fix it!!!!!

OMG - I cannot believe how terrible service has become at Nando's Horizon View. Last night I called to place an order for collection, the same way I always do - I ordered a quarter chicken, breast, very well done with a special request for the it be "burnt", with a side of wedges and full portion livers Mozam Paprika. I asked the lady to repeat the order and so she did. When I asked her for my order number she advised me that the system was down and that she wrote it down and I must just give my name when collecting. I left my house and drove to the store. When I arrived there was no one behind the counter and I had to wait +- 5 minutes for someone to come to the counter. To my surprise my order could not be found on the system so I advised the woman that the lady that took my order over the phone wrote it down. After searching they still could not find it. I had to repeat my order. I repeated my order twice as the woman behind the counter could net get it correct - eventually I asked to speak to the manager - (Nonhlanhla). When she arrived at the counter I had to repeat my order for a 3rd time?!?!?!?! I gave my order again (a quarter chicken, breast, very well done with a special request for the it be "burnt", with a side of wedges and full portion livers Mozam Paprika) The cashier repeated my order and to my astonishment there was a Mango and Guava juice on my order which I DID NOT ASK FOR and the liver portion was INCORRECT?!?!?!?!? Like ***? She removed the juice from my order and repeated the order again and this time there was a FULL CHICKEN on my order? I just gave up and walked out. This is now the 3rd complaint I am lodging against Nando's about the poor service and personally this is unacceptable - We are regular customers at Nando's Horizon as it is the closest to us and the food is delicious - and given the amount of money spent there over the past few months - I do not think a request to have competent staff is asking too much? Do the staff get trained on customer service and delivery? Do they know what to do and how to do it? Is it just complete and utter laziness or is it because I am white? They know me very well as I am a regular and I do not accept ******* at all - I expect to get what I pay for. Very annoyed and frustrated with Nando's - please do something as this is just getting worse.
