blacklisted my phone without consent

I had my device blacklisted by Vodacom without my consent over the weekend, after a number of calls to ********** (blacklisting department) I was advised there is no history showing my unit has been blacklisted this after i was advised in store the unit had been blacklisted also the ITC ref ( ********** 1) for blacklisting was given to me but the agents at blacklisting department insist its not the case but in the same breathe request that I go SAPS and do an affidavit stating i need to have my phone unblacklisted! I do not see the need for me to go anywhere to get any documentation as I was not the one who requested for the unit to be blacklisted. The Twitter social media had made contact and promised a call back to no avail as well
