Called Customer Service on 21 May to have service terminated. Returned all equipment via UPS. Received bill on 24 May for next months service. Called again on 26 May and Customer Service says account is still active even though agent read notes file saying service was to be terminated effective 21 May. Told agent I would not pay for service after 21 May -- no equipment and have moved. Promise of escalation and return phone call never happened.
Who do I call, because Customer Service can't figure the issue out?
