Very bad service

This afternoon, I visited the Foschini store at Golden Acre to return an item that I had purchased at the Foschini store, Canal Walk. Unfortunately, I misplaced the receipt; however, I was able to provide printed proof of payment that included the necessary details for the transaction. Initially, the cashier seemed unsure of how to assist me. She later consulted a colleague, who informed me that they could not pick up the transaction in their system and advised that I must return the item to the Canal Walk store. I expressed my concern about the 30-day return policy and explained that I chose Golden Acre due to its central location in Cape Town. When I inquired whether they could contact the Canal Walk store, the colleague informed me that she could only address matters related to the Golden Acre Foschini store not Canal Walk Foschini store. She also questioned why I was returning the item now; I explained that it did not fit me well and my schedule had not permitted me to visit Canal Walk sooner. I am disappointed with the level of service I received, especially since I adhered to the return policy. As Foschini is part of TFG, I expected a higher standard of customer care.
