Account sent to Debtsource,but no account with Adt

On 3/3/2015 I received a sms stating: \Your ADT account has been sent to Debtsource for collection.Regards Nnyana on ***. ***<br> I have never had an ADT account. Contacted ADT Herm**** and was referred to Janine Smith in Cape Town who referred me to Mr. Riekert. I am still awaiting their explanation regarding this matter. Phoned Nnyana but spoke to Nosibusiso and explained the problem. Still waiting for her to phone back with an explanation."
