FNB Private client service sucks

As a FNB customer for almost 10 years and a private client I'm disgusted by the useless service received from FNB. I app**** for an increase on my credit card limit on the 18 October 2019 and today (28 October) still not activated. And getting different answer on a daily basis. I need this increase limit to pay for security upgrade to be done on my house, while waiting for an investment to be paid out, after a break in at our property. Clearly I can't rely on FNB to help me . PLus my personal private banker is never available and always on leave, in 2 years she has never answered any off my call.
