Approaching two years of a delay in a claim payout SaR

Dealing with a claim through old mutual has been a nightmare. Almost two years they come up with different excuses when they have to finalize the claim and pay. Sometimes they call and raise your hope then later say it was an error. They write a letter saying after two weeks they gonna pay then later say it was an error again then months later they start the process from scratch again. It seems they don't want to pay or they have been bribed to delay the process. Their service has been unprofessional till this day...my kids continue to struggle financially while their father left monies for them. I'm so disappointed I even complained to The National Financial Ombud Scheme to investigate this claim...I wish and will encourage my father and others to cancel their policies with this company.
