All Spectrum customers should be afraid.  In the nearly 3 years since Betty Thomas’ senseless murder, NOTHING has changed – Charter Spectrum have not started doing pre-employment verifications, they have not done staff training so supervisors have an escalation process with a troubled employee, they have not stopped forcing arbitrations, they have not changed their policies on informing police of crimes committed by their staff – they have done NOTHING to ensure your safety.
You should complain to Charter Spectrum and demand changes are made.  And you should never allow a tech into your home unattended.  Always have a friend or family present at the time of the service.  As this case shows, they cannot be trusted into your home.
