Bad service

Hello there, I am writing this review expressing my overwhelming disappointment with the service I recieved recently from vodacom. I have requested my device (cellphone) to be blacklisted to their consultant, without any success they couldn't help me with the blacklisting because they couldn't recognize the cellphone numbers that got lost with the device, so the lady who was assisting me sent me the forms to fill and requested that I should return them to their blacklisting department with the police affidavit along with my I'd copy, I did that four days ago, but yet their blacklisting department only sent the acknowledgment of the email I sent on Monday. Up to date I haven't heard from them. I need the Itc number to proceed with the claim from my insurance but look like I won't get any help from Vodacom.
