Customer Service Non Existent

WOOLWORTHS I called Woolies online this morning to change the address on an order that I placed as the address was incorrect and I only noticed it last night upon placing another online order. I was told this morning by Customer care agents Zaakirah and Cindy that I can't change the address to have my goods delivered to the right place and i have to cancel the order and do it again but they can't fulfill the promotional price i paid? How are you servicing your customer? You have my money, changing the delivery address doesn't affect what I paid as the delivery cost is the same countrywide so what's the problem, is my order and my money not good enough? Is customer service not number one at Woolies? It's okay for my goods to be delivered to the wrong place but my money is in the right place, SHOCKING 😱 the price you pay when you make a mistake at Woolies😡
