I suddenly had money taken from my bank account with no idea who megaflix were. On searching the net I found contact details *******@megaflix.net and emailed them.
The reply: Upon checking, you had signed up for a 5 day free trial on our site and did not cancel or choose a plan so as stated in our terms and conditions you were upgraded to a monthly premium membership.
We have canceled your subscription with reference number xxxxxxxx and rest assured that no future charges will apply.
May we help you with anything else?
I did not sign up for any free trial, and how they got my card details remains a mystery, so beware!
