MFC not holding up their end.

Due to economic difficulty, I am one installment behind on my vehicle and struggling to catch up and I wish I could but at this stage it is impossible. Twice MFC have told me they can divide the arrear installment and add it to my normal debit order to catch up that way. I have also requested that the debit order date and account be changed. Both times they have failed to put these changes into effect. Now they constantly harrass me with calls and SMS's and the call centre agents doesn't want to know ANYTHING about the arrangements I made. MFC, follow up with Nikesh Jaimangal regarding this, he "assisted" me with the arrangement(he also doen't come back to me on email). Contact me for my account number. You always state, "Calls are recorded for quality and security purposes" go back to those calls and you will see I made an effort to square up with you but you didn't keep up your end. It's costing me a ton on debit order return fees!
