Angry Client towards Cell C

My phone has been blacklisted by Cell C and I called Cell C trying to find out how because I am a Vodacom Contract client. I was then advised to go and make a police affidavit and go into Cell C store to complete a un-blacklisting request form which will be sent through for my phone to be un-blacklisted.

I went to Kolonnade branch on Monday 5, 2018 and they emailed my documents to their un-blacklisting department. I have since called trying to make a follow up. Everytime I speak to their consultant I receive bad attitude and I am told my documents are nowhere to be found. I am totally upset and disgruntled because I feel like this is totally unacceptable more especially because I have comp**** with all the necessary requirements.

Can someone please urgently assist me in trying to resolve this and finally putting it behind me.
