i'm sick of this number calling me tried calling back they put you on hold blocked it now

I too have been bombarded with numerous calls from this and a set of other numbers, they are all Telemarketers, The calls came flooding after registering certain programs online, all of which promise not to give out any private information with any other sites or partners. I had all of the calls stopped, when I decided enough was enough and had my telephone number changed to a number that was out of circulation for several years plus.
It really hurt loosing a good number for another, not to mention, loosing contact calls from old friends and family that only had the number just changed. Now I use a Mobile number, and off we go again, but this time, I can block them as spam, which is exactly what these nuisance callers are. I've learnt that it is extremely hard to 'not' have a marketer bother you these days. However, it is really good having this site to come to.
Because we can squash and batter these lower than sewage bottom feeding nuisance marketers. if they however STOP calling after asking them, directly and discussing your number to be not called, and they do what is asked, then, helping thyn self works, which moreover is happening more than less. again it's those numbers that you ring back and run into a dial tone and never a human or caller ID, that truly want to drown in my septic tank of annoyance. Good luck with the ongoing fight, may you win, or at best get in a bite back...
