unsatisfied client

its the 4th time i am calling FNB regarding my personal loan. Fridays and Saturdays are worst. i am made to hold for 40 minutes. i end up hanging up. who is supposed to pay for the call? your service is bad. i went into a branch. i was made to sit on a phone only to be told the consultants have knocked off. but i was made to hold again for 40 minutes. i am going to change banks just for this nonsense service i keep getting from your bank.
