Harrassment due to a Third parties’ debt

I am writing this review as I am desperate to stop the harrassment that I have been going through at the hand of this Company. An Employee who worked for me in 2011, gave my number as reference when she opened accounts at various stores. She did not pay her accounts and MND started phoning me non-stop. In the beginning, I explained everything to them, gave them all her numbers and requested that they remove my number from their database. Still, since 2012, they have been harrassing me non-stop. These past few days were the worst! They keep on phoning me and when I block their calls, they persist and just phone from another number. Please please please I am begging you, stop this harrasment immediatetly! I do not owe you any money and I have had NO contact with Mrs Nomsa Hypercia Mngwenya since 2011!!!!!! That is, 14 years!!! Please do your work properly and track her down, so you can harrass her about her outstanding debt and NOT her ex-Employer who has NOTHING fo do with her debt!!!!! Numbers that phoned me over this past few days: ***, *** and ***. They have also sent me various text messages in which they state that they have been unable to reach me and they say I have to phone them at ***. I have done this in the past and explained everything to them, to no avail. Please, if anyone who works for this Company reads my desperate plea, please remove my details from your database so that I never have to receive a call from you again!!!!!!
