I'M DONE ASKING NICELY!!

I'm not a client of them, I don't to be a client of them, yet they've been phoning me now for more then 3 months. They phone at all hours, sometimes 2-3 times a day!? I've asked them(call center operators), beg them to please stop calling me, asked them to please remove me from their database, but they just keep on phoning. I block their calls, but they just keep on changing the numbers!!! I've tried speaking nicely, I tried swearing, I tried making threat, but, nothing works, they just keep on phoning back!! The Call center operators, are either extremely uninformed, or uneducated, because they tell me everytime they've no idea how to remove my cellnumber from their database!? I've reach a point now where I'm going to do something totally irresponsible, or go through the Judicial system to make them STOP!! They don't seem to understand the words, not interested, or leave me alone!!

I'm done!!
