what customer service??

i have called twice this morning just wanting to discuss the different credit card interest rates. the first call when i asked for a reference i was cut off, the second agent i spoke to, i was on the phone for 29 minutes and still did not get the answers to general questions: what is the annual interest rate, does the bank offer benefits if a client has more than 1 account or product with the bank... GENERAL QUESTIONS took 2 calls and more than half an hour to get zero answers.
