changing shoe sizes

on the 31st of January I had bought a number of items on my account. on the 10th of February I went to Edgars to change the size of my shoes and my son's shoes. I got to customer services I told them that I need to change the size of which they did something with card and told me they have credited me I should go get the size. only when I came back with the new sizes (same shoes same prize) I was told I cant get the shoes now because my account is overrun. I didn't understand because these shoes were already in my possession. so they took my shoes but I was not allowed to take new sizes. Even the so called manager who was called did not help either she kept on explaining the overrun account as if I am stupid. <br> <br> As for my overrun account which is not the point here. but I pay my account every month and I am sure I will be charged for the overrun even though they took the shoes back!!!<br> <br> I am very angry and frustrated with Edgars. That was terrible and very disturbing!!
