NO RESPONSE FROM ABSA " DISPUTES"

I have made a payment for an online order on my credit card recently. It seems that the service provider is a ********** company and I reported this to the Absa call centre. I received good and friendly service from them , although I had to make at least 4 calls. I was referred to " Absa disputes " with an email address , apparently you can't contact them telephonically. I have already sent two emails to disputes @absa co za , stating the urgency of the matter! To date I have not even receive an acknowledgement of receipt or a read receipt.
