NO GIFT EXCHANGE?

I received a Mother's Day gift from my sister who knows exactly how fussy I am, that she requested a gift receipt. I scouted three months and found nothing worth exchanging this item for until Women's Day arrived. The PMB Midlands Mall floor manager (Glenda) stated that I took too long to exchange the item (still sealed and intact with the gift receipt I may add) & the system won't allow it. The manager was out of town but she will get her to contact me as soon as she is back. I am still waiting, along with the complaints email I sent later that day via their site. Absolute lack of customer service and NO feedback is more disturbing than the fact that I can't exchange something I would never use!
