Emerald life is a **** and unapologetic about that

For the past four month ends Emerald was debit money from my bank account, R279.00 to be exact. I had no knowledge why this was happening so I called Standard bank for reversals. Recently I went to Standard bank for a loan application and was denied reason being "I reverse debit orders". I contacted Emerald life, filed a complaint and also went to their branch and filled in a cancellation for also mentioning a list of documents required by the bank i.e. written letter from Emerald life stating it was rightful that I do debit order reversals. Nothing has been sent to me, nor have I recieved a call from complaints department.

I called in, spoke to Mfundo (Supervisor) from complaints department. From Monday he has not sent me the letter I requested
