bad service

i called the call center to query mi updated on my cheque account they take me from pil**** to post and no one can help me at all. and the updated are faulty as i expected to have a certain amount left in mi account and now i have nothing an no one can explain to me why eventually they hang up on me what kind of a service is that i have been a customer for the past 12 years never in that time did i have a problem with my bank and people keep on saying that they had issues with them i never knew this is how they really treat their valued customers like this
