MY DETAILS USED IN VIRGIN MOBILE

I discovered that a contract was opened using my details in Virgin Mobile of which I do n t know anything about.Apparently I am owing them R2000,the cellphone account that I have opened was with MTN which was in August.This Virgin mobile is also listed on transunion and it affecting my credit score badly.I am aware of the account that I have opened since my employment date but Virgin Money is none of those account.This I declare a **********.And I becoming a victim of something I don't know.I cannot be held hostage by some ******** who is out there benefiting by using my details in that manner.I am a responsible and financially disciplined citizen.I will not allow myself for my financial freedom to be taken away just like that.No ways I refuse.And worst they even use my cellphone which I have been used for more than ten years to make contact with me and those threats imposed.
