Blacklisted for no reason

<p>My IPhone 5s phone no. ********** 41</p> <p>IMEI ********** ********** 8 was black listed for no reason in August. I was not aware that it was blacklisted at the time and took it to Have it repaired without success. And ended up buying another phone. </p> <p>I then contacted Vodacom on 21.11.2016 to check if my phone was blacklisted. They informed me it was and requested to have it unblacklisted. I have received notices to say it's open, but it's still blocked. </p> <p>I put in an MTN SIM card and the phone works 100%.</p> <p>1. Why was it blocked in the first place</p> <p>2. Why can't it be unblocked. I even attached an affidavit.</p> <p>3. I had to buy another phone as I use the phone for business. </p> <p> </p> <p> </p> <p> </p>
