Poor service and felt bad about experience

Hi there. I am very very unhappy about treatment we received at HOME ETC hemingways east london. Today my wife went to shop there and normally we do shop there . My son 18 months old was in trolley he pulled one of the item it was coffe plungers and it fell on the floor and broken. The managers yolanda duplessis that's what she said her name is . Forced my wife to pay for the item and when I ask her do you have any policy statement written on the wall that if customers break they should pay ? She said no . I ask her but how could you do this it's a small child . Then she starts argue with me . I left the store . I myself worked in a retail store customers have messed up our clothes we never force any 1 to pay because it's bad for the company. And how could she do this . I am very very unhappy about this I want them to return their product and give my money back. Otherwise I will take further steps and I want an apploogy. Thanks Regards Atif kahn
