MFCs appalling service

My car was recently reposessed by mfc due to me not being able to pay only because I work for south african airways and SAA is currently still not currently flying at the moment. When my car was repossessed I had the worst experience with one consultant named Bronwyn that handled my case. She didn't contact me and let me know what's happening, she was so rude and had no customer service what so ever that she actually told me that I have no communication skills....she huffed and puffed each and every time I called and she made me feel like I just decided to not pay my car premium because I can. Even the lady named esther who also works in the same place didn't get back to me with calls and was not helpful at all....when I finally got to paying the money to get the car back and I got to the auction warehouse to pick the car up, Bronwyn did not even communicate to the relevant people to make them aware I was on my way to picking the car up, 30minutes later then someone comes to attend to me....no one knew what they where doing. Even as I type this I have come to know when I called mfc to clarify when my debit was going off I was told that I'm still owing R1069 for storage costs and handling fees and tax....I had paid what Bronwyn has asked me to pay and I got the car back, now this lady tells me that they miscalculated. How is it that a big company like this employs idiots with no brains to actually miscalculate. I refuse to pay this because Bronwyn should have done her job properly and then released the car...I am still not even getting paid and I borrowed money to get that car back. I'm really really disappointed and shocked at such appalling service from such a big company such as mfc .
