Unhelpful employees, unwillingness to help

WesBank has been billing me for more than double my car installment from JUNE 2019. Now they want to tell me, I have to pay more than double my car installment per month but they cant even tell me why or how, I was first told this was because they had not received my proof of insurance, but i have showed they had received it when they requested it! I have called in multiple times and they can not even tell me what I am paying for, the woman that just now answered my call, explained that there were multiple things added to my finance that the company should of called me to get me to accept, i explained nobody called me or got any kind of confirmation and simply "transferred me", the phone call dropped. This is ****************.
