Home loan - poor service - insurance

I have a bind with Standard bank and the life insurance is crazy high, I have been trying for 2 years to talk to someone about this but when I seem to be getting close it gets sent to another department. Honestly, so much **** they happy to take my bond but the after service is horrid. it got as **** as someone calling me to set up a time to come and complete the life insurance medical then i never heard from them again. how can a bank be so poor when they making so much money on us??
