Poor customer services from standard bank

standard bank is the bank that has finance my car for about two years now, but they sending me monthly statement that does not have any instalment breakdown, i phoned them to inquire about the statement but i did not get any assistance from all the consultant that i have spoken to, the consultants are not even professional at all and they keep on promising that they will come back to me but never did. it is about two months requesting for the breakdown of the monthly payment that am paying but with no help. now am asking myself, what is that standard bank is hiding?, am so disappointed by the service of this bank and now am planning to get another bank to refinance my car. their service is very unprofessional and very poor.
