Harassment

I have on many occasions requested that FNB do not contact me on the phone if they want to advertise or improve on my banking (increasing loan amounts etc ) and that they should email me this information or I will call them if I need anything. On two occasions I warned that I will be leaving FNB if they called me again, but they still keep calling me. <br> This is starting to feel like harassment and is pushing me past the point of not bothering about the effort to move to another bank.
