Bad Service

Woolworths delivered my credit card via courier service in early January, however they did not disclose that they would charge me R155.00 for the delivery. I have emailed them several times and even went to the store for assistance but have received no assistance from either. The response I get is, I agreed to the delivery and charge telephonically and they will not reverse the charges. The charge for the delivery was reflected on my account in December and the card was delivered in January and they insist that I agreed to the charge. I feel that this is ********* for Woolworths to assume that I wanted the card delivered to my home and to not disclose the charges on the call they made to confirm the delivery and when they are questioned about it the response is ignorance. I don't understand why they delivered the card to me in January when the old card expires at the end of March and how I agreed to a charge that was initiated in December.
