Worst Funeral policy EVER!

I took out a funeral policy for my parents which I paid because both of them are pensioners.

My mother passed away 11 March 2018 and I called them to claim. I did send all the documents on 13 March 2018.

I phoned everyday and I keep on getting the same answer ... its with investigations

Yesterday the monthly payment was debited again ... Im still paying for my mother who is deceased.
