Woolworths internet banking not working well

On 20/03/2016 when I want to transact on Woolworths online creditcard banking when I enter a PIN it said to me wrong pin up until it locks. I have tried to reset it but it is not working. I have tried several computer but did not work. When you you enter card number and press reset those numbers disappear. I went to woolworths balfour park but they gave me a to call there call center. It aws the 29/03/2016. From 12h40 to12h52. I spoke to the lady by the name of LAVERENS. She promised me that she is taking the matter further they will contact me within 48 hours but since then no respond. The ref no. For that call was ***. I want this internet banking subscription cancelled as I m paying the service that that I am not using. I will need a refund for this month because I m not using it because of your system which the RESET button not working.
