Highly Disappointed!!!!!

I am so disappointed in the service I have received from Woolworths.I have communicated with them about 100 times regarding the error on their part and still have not even received so much as an email response. This has now affected my credit score.Can someone please pick up the phone and talk to me.This is not the level of service I am use to from Woolworths and after being a longstanding and loyal customer, I wouldve expected more from you.. Highly Disappointed!!!
