Horrible customer service at Woolworths

What is the use of Woolworths having customer service if they cannot help you instore and ask you to use the App and send an email knowing that noone will respond to your email anyway? I sent an email on the 11th till today I have not received any response let alone an acknowledgement of receipt of my email. This has seriously put doubt in my mind, I was clearly wrong to think Woolworths had good customer service. Even the way the teller spoke to me in Centurion mall it was appalling.
