Very bad service from Woolworths Financial Service

I app**** for the limit increase on my woolies credit card via app and it was approved and required documents and I did send the required documents, id , October and November payslips and bank statements. I have sent it to limit increase email, credit card and CLI email. Its almost two weeks now every time I call they said unfortunately there is no one to talk to in that dept I need to email. I have already sent 5 emails to them but still no response, very bad service.
