Colonial Penn Insurance Denied burial Insurance for my mother, after policy was paid in full and overage Philadelphia Pennsylvania

I maintained a policy for $4000 with Colonial Penn for 20 years policy # RP91687627 for my mother, paying every month on time, so much so , that they advised I stop making payments because I had paid the policy in full $4K and all additional funds would be just paying extra, and the policy now would be enforce until my mother passed, so I felt good that it was taken care of, only to find out when I needed the insurance (mother passed 03/01/2018) they informed me the policy expired in 2015 because they sent a letter to my 85 year old mother if she wanted to extend the insurance, she never responded so they expired the insurance, they were always in contact with me before but this time and said this is their practice to ask the insured if coverage is to remain. So they took my premiums and my extra payments and said nothing we can do for you, and literally hung up in my face. I asked them how did you get my mothers address as I nor she has ever given you here address to send a letter, she stated " sir thats not important" the policy has expired" I have other callers. Theres absolutely nothing we can do for you.

I stated your rep. told me I was paid in full and to stop sending payments, then she stated that person probably dosent work here anymore. Sir I have to go now and hung up. Now i have to find money to pay for funeral.
