Pathetic Customer Service

<p>My Mother Recently (November)Made a Layby on a few items at this exact store . However one item was not the right Size . She then went back to the store to change the size however they did not have the size and she didn't see anything else that she liked . She however asked the sales team for advice or to refund her , her money and she was told that there is nothing that they can do if she can't exchange it and they don't keep the size in the store...But how can she exchange if they don't have a size hence she requested a refund . However she does not have the First lay-by slip however that is no excuse to not help a customer . If the store can't do anything then what is to happen ??? I am highly disgusted in the Service that was recieved . I hope necessary actions can be taken . </p> <p> </p>
