Went into Halfords Peterborough today 16_08_24 to purchase some oil. Was told by the lady on the till I could not use my phone app for the trade card I would need the plastic card I was issued. I explained that I had used the app recently in other stores with no problems but she would not except it. The manager Dean the rudest person I’ve ever met appeared and after trying to explain to him that I had a card and the mobile app but he didn’t want to know and asked me to leave his shop. I asked his name he said Dean I said surname he said I’m not telling you what a professional manager. Have put in a complaint to Halfords waiting for a response.
