contact Vojta Nekvapil - 3rd Party support Manager - nekvapil (at) avast (dot) com and recount your experiences with the 3rd party support.
Personally I don't get why Avast ties themselves to this type service that scams their customers....clearly financial.
You do have option with your credit card company to call them and tell them this charge was fradulent....in that they did not provide the service claimed.
For me, I only use the Avast FREE and during install (select Custom) I turn off every install option(s) except the Shields.
IMHO, Avast has good shields but the rest is not worth the $$$.
I know that this doesn't make you feel better being out $175 but I think your initial instinct to not dive in was correct.
