On Monday 11th June 2018 at 15.20 I visited the Lidl shop in Madeley, Telford.. I picked up two items that had 30% reduced labels on and proceed to the checkout. Upon paying I realised that I had not been charged the amount for the items that was printed on the labels. I asked the cashier why this was?. I was told that the shop had run out of labels and was reusing the labels from a previous reduction but that 30% had been taken off the items original price (despite it stating a different amount on the label) and she couldn't do anything about it. I said I didn't think knowingly mis-pricing an item was an acceptable practice and asked to speak to a manager. Eventually a manager arrived (with no name badge on) and although she did give me a refund was extremely rude to me and repeatedly denied the shop was in any way at fault. I asked for the managers details and despite saying she would give me them repeatedly went on to explain how the shop wasn't at fault. After 4-5 more requests for the her name I was ushered away from other staff & customers I was then asked "Tell me why you have got a f***ing problem with me?". In utter disbelief, I again asked for her details, and said if she didn't give me them I would take her photo so that I could make a complaint. After yet another refused request I took the photo at which point she physically refused to let me leave the store and called a security guard who blocked my exit. I then asked if I remove the photo from my phone if she would give me her details, the manager again replied "yes" but once the photo was removed she still refused to give me her details!. I was verbally abused and sworn at in front of customers as I left the store and was told I was banned. I went to the trouble of reporting this incident to Lidl themselves and rather than address the incident with the member of staff they have confirmed my ban from this store without giving me any explanation. Lidl Customer Services have shared information about this complaint with unrelated members of staff who have then attempted to troll me on social media. Further underlying the complete lack of any standards at this company. This company will never receive my money again and quite frankly they don't deserve yours!
