Rude! Rude! Rude!

I have an account being collected by these people. Periodically they send out SMSs to scare the living daylights out of people where they state the recipient should confirm their chosen domicilium so the sheriff can come and deliver legal documents. This is done regardless of you paying you bill on time and as arranged! I phoned the call center and lost it with them for scaring pople with stupid SMSs like the ones they send about the sheriff. I get told by the call centre agent: "Sorry sir, the system does it. We don't have control over it." I asked to speak to the supervisor, hoping that my plea will have a little more substance if the supervisor talks to their IT people to correct this scare tactic. I got 2 sentences into my appeal and the fool just puts the phone down on me. Bear in mind: I wasn't screaming, but I was VERY upset. He didn't offer an explanation, just put the phone down! RUDE! RUDE! RUDE! Seriously unprofessional!!
