Shame on Woolworths

On 29th July 2022, I went to Woolworths mall of the south to financial service regarding credit cards. They tried to call head of but there was technical issues and I was told to call them or go to nearest to the following day. On 3rd August 2022, I called head office regarding credit card cancelation however they did assist. They lady who m I spoke said she's loading the contract and I asked her to send via email so that I confirm what was agreement. She promised however I haven't received it. This is not the first time, the other I called them regarding clarification of statement they never help.
