alarming: feedback that no feedback will be given

After being contacted by ABSA about ********** transactions on my card, I stopped my card and opened a ***** case with ABSA. I sent an email to ABSA to enquire about these transactions, but Samantha Adolph rep**** that no such transactions could be found on my account. When I informed her that they were still showing there on my screen, and ABSA had contacted me about them, and I had received sms'es for some of them, she informed me that she could not provide feedback by email (I recall, however, having received email feedback on ********** transactions in the past). I asked her to call me, but no response. I find the discrepancies in ABSA's handling of my case of ********** transactions alarming!
