being charged incorrectley

Good Day<br> <br> i'm experiencing many difficulties with online shopping. they first time i was billed twice woolworths had refunded my money back and apologised, I had a late delivery with my products when I got to a woolworths store to return it and ask for cash back they didn't wanna refund me but gave me a gift card instead I had to take off from work go to the bank and go to the Woolworths Store to resolve the matter the store couldn't help me.<br> im very disappointed in the service i'm receiving I Cant not keep taking off every time i'm being charged extra and not receiving my goods I'm always working and cant take off to go to a store that's why I do online shopping<br>
