Delay in retirement policy payment

On 05/09/2022 I contacted Old Mutual in order to approve payment of my retirement policy and it was approved. I was told it would be paid within 15 days. I then contacted Old Mutual today (20/09/2022) to confirm the payment, only to be told to wait another 15 days. This is both frustrating and unacceptable as I have creditors in the form of my landlord and my daughter's school who are expecting payment from me this week. I am now stressed out and feel truly let down by what I can only describe as dismal customer service from Old Mutual. As it is I am telling my friends and relatives to start shopping for another insurance provider so they don't suffer the same disappointment I have.
