Purchased ready meals chicken tikka but when I got home one of them was prawn tikka put on the shelf with the chicken ones ,, phoned Tesco spoke to staff member and they said bring it back with receipt and change it , I drove back to tesco and customer service staff said can’t exchange it as once purchased you only have 20 minutes on fridge and frozen items. But it was 31 minutes since I purchased it ,, doesn’t state this in store isles or near fridges it states it by customer service desk ,, so make sure you go to customer service to read the signs on terms conditions rules. Before you do any shopping. , traffic today maybe I should of gone over the speed limit to return it within 20 minutes
