Old Mutual - where is the service?

I am a registered Tax Practitioner and I have a client who has an issue with two IRP5 certificates issued by Investment Horizons, an Old Mutual fund. The directive information is incorrect and we are unable to file the client's 2023 return. My client has contacted Old Mututal almost daily to ask that they do the re-issue. From being told they will assist, to them denying that he ever had a fund with them, the sage goes on and on. It has been over 6 weeks, and of course, the SARS penalties for late submission continue unabated. I am writing this review in the hope that someone at Old Mutual does care enough to note the review, and will give me a call so that we can sort this out.
