After visiting your chesterfield store on sunday the 8/01/17 to have a look at microwaves,we found one we liked but no stock we saw an assistant who was dealing with another customer after 10 mins she noticed us and said she would be 2 min so we hung around having a look at other things after 15 mins went to find her and she had gone not impressed eventually we found someone who told us there was none in stock but we could go to sheffield i told her not to bother and left the shop .having worked in retail for over 20 years and having it drilled into colleagues about customer service i think you might have to re visit yours probably retrain your colleagues
