Treated like trash

Dealing with this department at Nedbank is a nightmare, every time I call in I get treated like trash, am asking for a simple thing outstanding amount, the guy by the name of Kaylan put me on hold for more than 5 minutes and he comes back and says am owing around R52797.22 . when am asking for the exact amount he says he can't tell me that i must wait for up to 14 days to get feedback, what if i want to settle this account and close it, i find it very bad to wait up to 14 days just to get a settlement figure, can someone please have a look at this as am not really satisfied, firstly i was told that my amount owing was gonna go up because the hijacked vehicle was found even though it's not drivable but i was penalised for finding my car, i really don't understand this, I have been paying from 2013 the sum of R1500 per month until today but my amount seems to go up instead of going down, whyyyyyyyyyyyyyyyy really why are you guys doing this :( :( :( . even when you leave a message no one get back to you,
