horrible service by vodacom, ignoring customers emails

My phone was ****** on the 01.05.2018 and I blacklisted it, my phone was returned to me the following day now I regret why I unblaclisted my phone because to get it unblacklisted it’s a nightmare with Vodacom. I have submitted the form and affidavit as requested by them but my phone is not unblacklisted.I have sent 3 follow up emails but no one responds , I called customer service and they advised that they don’t have the number for their blacklisting department I HAVE NEVER BEEN SO FRUSTRATED IN MY LIFE BEFORE WITH A COMPANY THAT CLAIMS TO PROVIDE SERVICE .Vodacom PLEASE UNBLACKLIST MY FLIPPIN PHONE PLEASE

This is the ref number i was given by the unblacklisting dep EC-1JEN-1CCIA9.
