I have just had £74.99 taken out of my bank account why and how?

This has happened to me, £64.99 has been taken out without authorisation. I want a refund immediately

Hello Tracey,

You have been charged £74.99 for the renewal of AVG Internet Security Multidevice (1 Year) subscription recently.
Since auto renewal service was enabled for its first purchase, this charge was made automatically.
We did send prior email notification about this process and the charge that is going to be taken.
As per your request, we have initiated the refund for this charge and an email has been sent explaining its status.
You will get the amount credited within 7 business days.
Thank you.
Please can you tell me How and Why you have taken £74.99 out of my bank account without me knowing?  I DO NOT WANT THIS SERVICE,  I CANNOT AFFORD FOR THIS MONEY TO LEAVE  MY ACCOUNT.  PLEASE CAN YOU REFUND THIS.
THANK YOU
