Prudential Financial Customer Service Issues

My spouse, D.W.R., born on 11/25/[redacted], with the last 4 digits of SSN [redacted], purchased a $[redacted],[redacted] 10-year term life insurance policy a decade ago. I recently discovered it's not a lifetime policy. He mentioned extending it six years ago, but I can't locate any documentation. He relinquished my rights to a 50% survivor benefit on his UPS pension, notarized somehow. With no savings, our house foreclosed 13 years back after 30 years of mortgage payments on two homes. We acquired a house with a VA loan three years ago. Despite working 25 years and raising two children, my monthly SS income post-tax and Medicare is under $[redacted]. Monthly expenses exceed this by fourfold, and he has no burial coverage. His undisclosed 401k withdrawals and the policy renewal cost of $[redacted] (previously $[redacted]) challenge our financial stability. Expiring this July, the policy's renewal is looming, possibly leaving me financially vulnerable. The uncertainty is distressing, and I seek guidance on safeguarding my insurance coverage.
