FNB bad for business

I spoke to my Private banker on the 12th December regarding an issue with my risk profile with FNB Temp loans. My issue is as follows. I wanted to increase my credit card limit. I was told that this cannot be done due to the fact that I took a few ATM temp loans that negatively impacted my profile. I spoke to my banker and advised him that I was told it would boost my credit rating. He sent a request for the ATM temp loan to adjust my risk profile. The lead time would have been 10 days from the 12th Of December. Since then I have not heard from him. When I sent a follow up mail I received a response stating he will only be in office on the 8th January and that other bankers are attending to his mails. I have sent 3 mails to them directly as well and I have had no feedback. The service is utterly pathetic.

Please note I am in China and I can only be phones on the following number +***103 or by email.

Since this I have already app**** with Nedbank for a Credit card and it was approved.
