Bad customer service

Im so sick and tired of Wesbank and their pathetic agents that don't know how to do their job, first put me on hold, send me to a different agent and dont even to bother to call me back when I get cut off, nobody is able to give me answers maybe this is the best way to get their attention I send email and nobody gets back to me, I have settled my account and to my surprise I have an outstanding amount that nobody can account for and tell me where it is coming from, I request an explanation and honestly cannot wait to get released off this contract. A word of advice if you want car finance dont go for Wesbank their service and agents are pathetic
