What pathetic service both in store and "client care"

I did a purchase at the kolonade mall foschini store last week Sunday and was advised by one of the sales agents to consider buying one of the jeans "smaller size". Today, a friend of mine went to the Grove mall foschini to exchange one of the purchased jeans which was a smaller size as per the sales agents advise and was told she could not be assisted. I immediately called client care only to be told I can only be helped 5 to 7 days from today. Does that mean, the person who drove almost an hour to the store must wait there until they decide to help her or, she must drive back home empty handed and wait till Foschini decides they want to help her. On whose petrol. Rishka in client service has the nerve to tell me it's probably because the exchange was being done at a different store than where the purchase was done. Despite me explaining the distance traveled. She has the nerve to tell me why did I not read the receipt as it contains terms and conditions. Bull**** service continued with my poor friend waiting in store while I was home on the phone with an impatient idiot who could not even show a simple empathy towards the client. Consumer watchdog needs to be made aware of this supposed "terms and conditions" that are not even read to us in the store when making purchases that you are restricted to one store while making purchases and exchanges despite you having slips as proof of purchase. You will never see me again in your stores and I will make sure this does not go unattended. Airtime, petrol and time especially in this time of covid should be used valued but no, foschini continues to treat a black child as an idiot and they think they can get away with it. I'm sure if this was a white person, this would've turned out differently.
