Worst Custoner experience and poorest customer service

I purchased a gift for someone but took the wrong size. I contacted Cape Gate Shopping Centre where the item was purchased and they advised that Canal Walk has 15 in stock of the size that we needed. I then call your Canal Walk store and that in itself was a mission as the phone rings for very long before being answered. Eventually someone answers amd puts me through to the mens section and I speak to Deon. He advised that there is only 1 in stock after placing me on hold for a long time, even though their system shows 15 according to him. I then ask if he can keep it for me as I will be driving through as I'm a 45 min drive away and he says no he can't because the item is on special. I say that does not make sense as I cant be driving all that way and then the item is sold. I then ask to speak to a Manager and he gets a guy by the name of Nigel to assist. After explaining to Nigel, he says no he can't help and then says even if the CEO of Woolworths must ask to keep a sale item aside we can't do that. I then say so what if I drive all that way and then the item is gone, will you reimburse me for time and waste of money, he says no I an take it up with the Head Office. After asking for his surname, he says im not giving it and i can take it up with their Head Office. Like really, what **** is this. Your slogan should be "We Make No Difference". Now I understand why people support Shein and Temu. Thanks for nothing. Crazy part is, I will return all the items purchased along with the one top in that order that I wanted to change and will gladly cut all ties with such a useless business. With this attitude, I'm surprised you still in business. What a waste of my time and energy. I will surely not support your business any longer will continually be a demoter of your brand.
