Avast email contact? Multiple products paid separately

[mrgv11]

Hi, Been using Avast for years, very happy with the products, though I have a question on billing/separate items fees/adding products.  I have been round and round several times in FAQs and now look for a email address to contact with my questions, can any one help? 

I have Premium with added Clean up, VPN, and wish to add AntiTrack. I am also paying separately for AV for my mobile

Is there a better way to save/pay? say as one multi package? (Also my subs for each end at different times)

thankyou
