Edgards/RCS keep *****ing our money!

In April, we paid up our account and asked for a closure letter. No letter received. Now we were harassed for money daily and discover that we are still being billed for life insurance. Sick of the fight, we paid this and have requested again that the account be closed but now nobody can close the account. What is going on? RSC has taken over Edgars but it's a disaster! Someone please contact us to close this account!
