Breach of POPI Act and Bad Service

Requested a withdrawal on my investment and was advised it will take 5 to 9 days. Later received an email advising that my bank verification failed however to my surprise a different client's sensitive information was attached to the email. Further my contact details was changed without my knowledge and no one could account. This raised a huge concern that wrong information and contact details is changed after my notice to withdraw. The notice was done on the 1st March 2022 and to date no one has taken time to call or follow up on my query. i am the one who is calling for feedback after such a breach. I am frustrated and i want to take my money elsewhere. It is frustrating to learn that a big institute like OLD MUTUAL could recklessly deal with clients information and not even apply the POPI act regulation.
