Still waiting for service!!!

I have been a member of FNB for 22 year and I am 31 at the moment. I have a platinum credit card and tried to do an increase of my credit limit on my internet banking profile. I selected the limit increase only, however, it upgraded my credit card and gave me a limit so huge, I could buy a new budget entry car! So ridiculous. I immediately called the platinum credit card division to cancel the credit card upgrade as well as the limit increase. Vusi kept me on hold for 10 minutes in order to email the request for the cancellation, this was tuesday the 19/01/2016, i called the next day and was told that they will still attend to it. Then i called on the 21st only to be told that the request was just logged on the 21st and after asking them to escalate my request i was told by the admin department that i will have to wait my turn in the request. This is absolutely outrageous. Affter keeping me waiting so long, and now that attitude. Today is now the 24th and i still await a reduction of the credit limit and the downgrade of the credit card. If this is what loyality gets you then i suggest that people take their business elsewhere. FNB is not worth the praise i have always given them.
