Charged for Avg when unaware

Hello Linda,

I will check this for you.

I'm unable to find any recent charge taken from this email address.

I have sent you an email, please reply to that email with the requested information to proceed further.

I have recently reviewed my bank statement and have been charged £49.99 for something that I was not aware of. When I have used Avg it has been for basic protection which had no applicable charges. 
l need this amount refunding and for any future payments from being collected.
I have also checked all of my emails and none have been received to even make me aware of the amount which you intended to debit from my bank account, if I had been aware of this I would have cancelled it with immediate effect.
I need to know what you intend to about this?
