very disappointed

Ive been a client with fnb for 15 years this is the worst experience ive even had with a bank. Ive been trying to upgrade my credit card its been 2 weeks i have to phone everyday hold for 10-15 min and then they tell me the same thing I've send through the docs requested they can see it on the system but nothing happens they escalating it Whatever!!!! If i don't get this sorted in the next few days i am changing bank!!!! Terrible and i will tell everybody how bad fnb is!!!!!!
