STOP HARRASING ME AND BEING RUDE TRYING TO CONVINCE ME TO GET A TRACKING DEVICE!

They keep phoning me on a weekly basis. EVERY week I tell them that I am not interested, I cannot afford ANYTHING additional at the moment (If I have to choose between bread and a car tracker I think that is a no brainer), I ask them to stop phoning, and tell them that I cannot speak while I am at work. Today a very rude salesperson phoned, telling me that I need a tracker and that I am rude to not want one and then he puts the phone down in my ear. Even if I did have the money to get a car tracker you will be the VERY LAST option on my list of tracking companies! No wonder your reviews are so shockingly low! STOP CALLING ME! STOP HARRASING ME! IF I SAID NO, I MEANT IT! I don't need anybody to try and convince me!!
