Woolworths bad customer service

I have been contacting Woolworth's with regards to my account, I want to know what my outstanding balance is, but I have received no response, first email was sent on the 7th of August, a month later, no response, not even a automated response. I don't understand how you can claim to be one of the shops with the best products, yet your customer service in your financial department is of the worst. Pathetic.
