Kindly Stop Harassing Me

Please let me know how I can get rid of your annoying telemarketing campaigns for upgrades once and for all. I am called several times a day, even on the lines that are for my dependents. Each time I have to say I am not interested. Each time I am told that the agent marks me to not be contacted again. Each time, there is no evidence of previous confirmations of opting out. Telecomms? You have ZERO Comms. You abuse the fact that you can call unlimited time to HARASS people.
