MFC Poor lack of assistance and commitment

I was unemployed for about 3 Months but still made at least 60% of my monthly instalment to MFC. I started new employment in after the 4 month whereby my account was handed over to collections. In an attempt to resolve this matter I asked MFC what can be done to prevent collections of my vehicle and it was clearly said that I need to pay R17 000.00 to prevent my vehicle from being collected. I however went and paid R29 000.00 (R12 000.00 more) and notified the person of MFC whom I made the arrangement with who told me that if the R17 000.00 is received that the arrears amount will then be added onto a contractual extension. THIS NEVER HAPPENED FROM MFC when I made the R29 000.00 payment and then started paying my usual monthly instalment of R12045 now for the past 2 months. This morning I received a call again from MFC and the lady who phone me was RUDE beyond belief and extremely arrogant and did not offer any help of any sort what so ever when I explained to her what was arranged but never sufficed from MFC.

Now I am looking bad as per MFC's poor lack of commitment
