Bad customer service that has no empathy

Were I am I'm very angry with the service of Lewis stores, my wife passed away in the early morning of Monday was mourning and arranging funeral at home and all the importance. Lewis called my sister and she explained to them that I lost my wife she would come and make the payment in the coming week on Wednesday, worsen of the situation they called on Saturday day of the funeral that we must come and pay, I lost a wife not a dog I know that I have to pay and as a cultural person I had to follow the procedures, death is not something that we choose. Now I don't understand that the responsibility that need their attention because they have new account at Lewis. Just know that the funeral and death come and pass so we go back to our daily routine. You lack empathy
