FNB under delivers on turn around times and communication

So after my first complaint with regards to my credit card limit increase, I get a private message on hello Peter saying someone will contact me which they did after 24 hours, I took them through my income & expenses and they requested my investment account and my bank statements which I sent through to them on the 10th May, I then get a mail from Rahul Singh telling me that the credit department is attending to my query and they will get back to me after 48 to 72 hours. Today is the 18th, a week later and still no feedback from FNB..... What poor levels of communication & service..... Disgusting to be honest
