I’ve always shopped in your store but from today I will never go back. I was told to go to checkout 4 which I did but let another customer in front as she only had a few items. I loaded my shopping in the cart and scanned my debit card. The reader said to put card in, I let the cashier know just so she would instruct me to do so. Her attitude was very aggressive stating if it says put card in to do it. Stating after 3 uses of card u have to put card in. I said I tried that the last time and was stopped and asked to scan card again. She went onto say no that does not happen.Customer service skills and her attitude was terrible. After collecting my receipt I did say I’m not 5. She then went onto say in a loud voice and I’m not 5 either. I returned cart and went back to ask the lady’s name (I asked in a polite low toned manner)and she was chatting to 2 other staff members discussing me and laughing. She gave me her name and said I don’t have to give you my name and shouted I was rude. I said she was rude and she went onto shout get out get out several times as I was leaving. I have never been spoken to like that by no one. I will take my custom elsewhere in future. I shall be writing to head office regarding the customer care I was given. At no point did I shout at her and please review ctv. I can’t express how insulted I felt and how aggressive she was. I have always followed any instruction given by staff at any store and thanked them for service. I’m sure this is not how Aldi would expect staff to communicate with customers. I am very disappointed and will make a point never to shop in Aldi again if that’s how I will be treated. All of the staff I have been served by in the past always had excellent customer service skills and were very helpful. This lady needs some training in customer service. In no way did I disrespect her but was made to feel that I did something wrong by asking for instruction on the card reader.
