Charging a cancelled credit card

How does this company AVG collect money using a cancelled credit card???  My card on file has been outdated and cancelled do to being stolen. But they get their money anyway $106.99  out of my account without me knowing until the end of the month.( yes old school, still do paper statements). My bank for one should not have let it go through!! They will be called.  AVG  so called CHAT room  is open 24/7 , false. Have been waiting for 20 minutes 5th inline, then sign pops up "CLOSED" . Time to find another security system… HERE TO SUPPORT B.S.  Last time I use this outfit…
If anyone knows a better system let me know.
