NinetyOne is poorly run and offers appalling customer service

This isn't the first time we have had appalling service from Ninety One, but this time round it has been particularly bad. In April we submitted the correct forms to request that our ex-financial advisor be removed from our investment. Now, 5 months later, this still hasn't been done. I've made countless calls to their customer services, left messages, got reference numbers and followed up via emails - all to no avail. In addition, our ex financial advisor has continued to get his commission, even though we requested that he be removed 5 months ago. I am now going to lodge a complaint against Ninety One with the Ombudsman, as they should not be allowed to get away with such sloppy customer service. We will definitely NOT be investing through them again nor recommending them to our colleagues/friends. AND our initial request from April has still NOT been actioned. If their service is so bad, one wonders how good their financial ability is - they seem so badly run for a financial institution, it worries me about having any investments with them.
