MBD *****ULANT CLAIMS

I keep getting calls and sms's from this company telling me that I owe them for bought Standard Bank debt. I am sick and tired of this harassment. I have sent emails to an Ouma requesting information about this "debt" but have received no response at all. Further, this company sent a summons to be delivered to me for this "debt", but when I called the company apparently no one can assist me except this Ouma, who is only accessible via email but I get no response to my emails. This summons was sent to my new address where I have been living only for the past 6 months, so my question is how did MBD get my address. Was my credit profile accessed without my permission? Which is *******. I was told by Ben Teffu that Standard Bank gave it to this company. I will see if that is accurate as I will be laying a complaint against Standard Bank for this as well.
