MFC stuff up

Last year I was forced to go on disability, I did not get a salary for a few months which resulted in my account going into arrears. We contacted mfc and with a huge struggle and begging mfc said they would wait for my Pension fund to pay out where upon I will settle the outstanding amount. This happened in September. We (my husband handles my account) gave instruction to mfc to NOT CANCEL MY DEBIT ORDER.....but they did, then 3 months along the line, they came back to say that I am in arrears of my account, which was impossible because according to me the debit order was going off monthly, my bank never told me there was s debit order that didn't go through... We contacted MFC and told them whag happened....because this was their mistake, not ours...someone on mfc's side obviously didn't do their job.....the flatly ignores us and bully's us with constant threats of taking back my vehicle but NOT ONCE did they apologize for their mistake they just carry on with threatening us. We've been struggling to get this account up to date now. Instead of assist us with a restructure they are just absolutely rude and do their best at making our lives hell. I am sending this complaint because the person who is "assisting" us with our account doesn't listen to us, he just bluntly carries on with his threats. Please can you give us someone with empathy and a person who has actual customer communication s****s to contact us with this issue/problem please.
