I never received the refund that I was promised after a serious bug
Malwarebytes bugged on an update and kept on downloading the update, until all my surf volume was consumed (after an hour) and a 50€ worth additional volume was billed to me by my phone operator.
This is already inacceptable, that's exactly what we expect to protected from by an application like malwarebytes.
I contacted the support, who recognized the fault in their update and offered me a refund of my malwarebytes subscription, a lot less than what I had lost, but ok I accepted that.
But I never saw that refund.
I guess I just lost money AND time.
