Poor sevice

I have discovered that my ID has been cloned/****d and was used to obtain my bank statements, attempted to open accounts with Cell C. On Monday (25/01/2016) Cell C agent called me to check if I was expecting any delivery from Cell C and I informed her that I was not expecting anything. She then alerted of ******** activities happening with my **** personal information. I then phoned South African ***** Prevention Services (SAFPS) who requested that I must furnish them with a cancellation letter or a letter indicating that there was an attempt to de***** the company with false Identity. I tried several times to obtain such letter from Cell C but have been sent from pillar to post (i.e. from customer care to cancellation department from this to legal department and finally to ***** & risk) and in all these departments I have gone through no one was unable to help me. Can I please request someone higher up in the ranks to help me with this letter? This will not only protect me but other organisations that may be de*****ed by this *********.
