My children have no christmas clothes because of Edgar's staff

I am very dissapointed at the Edgar's staff including the manager at the Edgar's store in Canal walk. I went to the store yesterday to exchange clothing that was bought at the store, I did not have the receipt and before I started choosing the clothes to exchange I asked a staff member if I could do the exchange without the receipt and she said yes I can. So I went on and chose the items I wanted to exchange with I then proceeded to their very long queue. When I got to the till I explained to the woman at the till that I'm here to exchange the items I have with the items I just picked and, I told her I don't have the receipt she then asked me to take the clothes out of the bag and I did. As soon as she saw the clothes she looked at me and told me it's going to take too long to exchange the items and she will not be able to do it, she called the manager and the manager told e the same thing. So my kids are without Christmas clothes because the staff and manager at Edgar's Canal walk refused to do an exchange for me, it was not because it couldn't be done it was because they were lazy to do it and now my kids are stuck with clothes that are too big for them to wear that will probably fit them in a year. I hope the Edgars management gets back to me with this and because this is unacceptable.
