Why am I being harrassed for my family's debt????

<p>My brother and my own accounts are spotless yet we are being harrassed for my sister's debt who has emigrated. The woman who called me from MBD this morning threatened me that she will harrass me until my sister calls her. Who do you think you are???? We are getting post sent to our home. If my sister ****s someone, does her whole family get charged for ******? Further to this, my sister and her husband are unemployed where they are living. We hardly hear from them as they can't afford to contact us. Must I make a specific call that will cost me a few hundred rands for your company??? I have a job and cannot get harrassed by calls that will affect my job. Take my number off of your system! I am already paying 2 accounts for my sister out of my own pocket and am tired of this!</p>
