Issue not resolved - 3rd complaint since December

It is the 3rd complaint I have to post as my issue with ABSA has not been resolved. On December, 3, 2014 I visited ABSA Cresta branch to cancel Credit Life Cover for the personal loan as I have my own products. The necessary documents were signed. ABSA consultant Phillips Joseph sent file to Head Office. After second complaint (posted on January, 19, 2015) I received a call from ABSA representative (I didn't catch her name). She promised that February deduction will be adjusted without Credit Life Cover and I will get refund for January. Unfortunately it was empty promise. The debit order was deducted on February, 28, 2015. Credit Life Cover was deducted. No changes. No refund for January. It's been 3 months. Will it be sorted out eventually? Is it time to contact Ombudsman for Banking Services? OBS asks to allow \20 working days for your bank to respond to your complaint". Well"
