disturbing manager behaviour

please take note of this complaint , the way in which your managers interact with customers. I went in 6 30pm to collect my order which i had called in for , simply a collection. I waited at collection counter about 5 min , with staff up and down noting i am standing waiting for order. i eventually call for someone's attention to assist on the end of collection point , the people packing the orders. In the interim they have come to assist and give another customer their order at the same collection point as i who came in after me. (please note all on camera) Sindi the manager eventually comes out to which i then say is there only 1 person assisting on peak time which was the cashier taking orders . Her response was there is only one 1 cashier get used to it! What manner is this to deal with customers?? i then responded excuse me ? i will complain not deal with it, i am then told i expect the cashiers to stop the client they dealing with and assist me - WHERE DOES THIS COME FROM? NOT ONCE HAVE I EVER COME IN TO A COLLECT A ORDER AND ASKED THE CASHIER BUSY WITH QUE TO ASSIST ME , i wait at the collecting counter like everyone waiting to collect , however we expect to be assisted , and not wait for the cashier one person who is constantly taking orders with que. I want the cameras to be looked at to establish why this comment was made as you will see never once have i interuppted the cashiers for my collections. I have been coming religiously 2x a week for the last 5 year , 2x a week to collect from your store, so very easy to look on footage in week IF I HAVE EVER INTERUPPTED A CASHIER WITH CLIENT ! i am highly offended by this and insulted in the way treated by your manager SINDI in store. Besides the rudeness in comment above of "DEAL WITH IT" , i will not be treated like this and accused of nonsense, I stand in the collection area and if someone can come out seeing a bystander waiting for order hands it to him , why i am not assisted? i would like a senior manager to call me regarding this as i am taking this very serious.
