Mtn sales agents

So Mr husband's contract comes to an end and he has expressed that he is no longer interested in renewing it.. Mtn calls him almost every day and if they can't get hold of him they call me. I just told this last lady that he is not interested and asked if they can flag him not to call.. But she put the phone down in my ear.. Way to go mtn!! Employing some stellar sales agents. They might not all be like that but this one is lucky I didn't get her name.. Disgusting behaviour..
