TFG is harassing me

Foschini (as per True caller) is harassing me, since last year! Each day I get lots of missed calls from this number ********** and even when I remove them from my block list to actually hear what they want, they buzz me and then hang up. This is getting too much and is causing me distress because each day I get notifications of missed calls from them. When I call the number, "it does not exist". They have now started to harass my man as well as he gets the same buzzing. Please remove us from your buzz list, unless y'all want us to close our accounts with y'all. WE DO NOT OWE Y'ALL ANYTHING SO PLEASE STOP IT WITH THE HARASSMENT
