No Mercy, Caring or Understanding of enquiry

Since I hardly receive my bills through the postal services, I requested to receive my Woolworths bill electronically. I received my first bill electronically in March. I noticed that it is mentioned on my account that I am in arrears. I sent an email to enquire when this happened since my own records show that I am up to date with my payments.<br> What has happened is that I have paid my November 2014 bill on 30 November 2014 and my December 2014 bill on 9 December 2014.<br> Since I was so nice to pay my December bill too early according to their system, I am now in arrears and are charged overdue fees. <br> I enquired again and was informed by Mandy Davids that they do understand my frustration but a overdue fee will still be charged. As she put it, \It is with regret that no adjustments can be made as Woolworths do not recognise advance payments"Does this make any sense?<br> """
