Pathetic service

I have been with Nedbank for almost 5 years now and their services just keep on getting worse. I am really just considering closing my account. About two weeks ago I upgraded my account. Since that phone call I have received now other phone call or communication since then but the are very quick to take the upgraded account fees. They said someone would contact me and come to my work for me to sign the documentation with regards to the upgraded which did not happen. I don't understand how the norm in general has just became for any business to deliver **** service and get away with it unless your rude or fight about it.
