1Life : terrible support

I notified 1 Life in writing on the 2nd of April that I am cancelling my policy. Only 2 weeks later I received an email from them that my request was sent to the cancellation department. I tried to follow up but no one was responding. At the end of April, they took another premium, after which I asked for a refund. But still no response. This is terrible, just wonder how terrible they are when it comes to paying claims.
