BMW Financial services

On the 14 January our company requested what was outstanding on our account. BMW Finance customer care emailed Ms Palesa Tshabalala that we were R8759.44 in advance and emailed us what would we like to do with this amount. I advised that I wanted to reduce the term amount and was sent a adjustment confirmation letter. since then until today Blake Attorney and BMW finance call us 2/3 times saying we owe we are outstanding R8729.80 We have paid an additional amount of R4400.00 to stop the calls and frustration we are feeling, but BMW still say we owe over R8000.00. Numerous request have been done telephonically with Lydia 031 *** of Blake Attorneys and sent her the emails as proof of what has transpired, and requested that everything just get reversed so we can go back to normal and nothing seems to be done except to harass us. Can someone please sort this out all we wanted to know was how much we and and when will our last payment be due
