Result of your request:
800-555-1212 -- Nemyst -- Confirmed quality number with confirmed name, removed from our call database -- Placed on working number selling list
I used to be so kind to call center workers, asking them to remove from the call list, with all the please and thank you's i could give. But most of the call centers would call back (most likely due to the above).
Now i tell them to "Fuck off", be abusive and swear my heart out. Surly that gets you put on the "black list" and removed from the system?
Works for me in the UK.
I feel sorry for the staff, but at the end of the day, their job is to piss people off and they know it.
