TOTAL lack of response / resolution

Samsung S3 un-blacklisted 29/10/2015. Telephonic calls to call Centre and branch saying phone not activated. In the mean time used Samsung neo inferior phone to stay connected - very frustrated. Was told to try a sim-swap on 08/01/2016 - no difference. On 19/01/2016 went to branch and agent did online report after testing with no resolution and verifying still blacklisted. On 20/01/2016 received sms confirming phone definitely un-blacklisted and will work within 24 hours. Untrue. Between this time my phone was also reset and some data was lost - very frustrating. Calls back and forth, then on 17/03/2016 went to branch where agent logged another service request. On 31/03/2016 I went back to store to report same status - ALL other sim cards work on my phone except my VOSACOM contract sim card. my Samsung S3 has no been \useless\" and not is use for 4 and a half months and VODACOM has offered NO SOLUTION!"
