Vericred calling the wrong person daily and have no respect for ones resquest to stop calling them.

I have no words. I am shocked to the core. I have been contacted over months by this company. They have been calling me daily looking for someone who i advised them they have the wrong number. this happens daily sometimes twice daily sometimes thrice daily. Every day its a new person. I requested them to remove my number from there system and was informed it was done. 2 hours later a call from the same company. I requested to speak to a manager on more than one occasion and was told they will request a manager to contact me which never happened. I took down an email address on my last call from an agent whose name I wont mention on this platform and the email I wont state on this platform. I was frustrated and stated to put big bold notes on the system that the next time they call me I will give my reference number and swear the caller non stop till they cut the call. Now that I am calmed down I don't think I will swear someone who is just doing their job but I also cannot be getting calls everyday twice a day in the morning waking me up and in the afternoon. Sometimes i run to the phone dropping everything thinking its a cleint only to be spammed by a company who i asked politely to remove my number. This is unacceptable and i am literally willing to drive to a branch to meet with senior managers and sit there until i see my number is removed. what more can one do someone please help me.
