Poor service related to Vodacom Look for Me

I had Vodacom “lookforme’’ on a phone successfully for a long time. I upgraded instrument late last year and found that the facility did not work. Phoned Vodacom business help line and was told to call Look for me line, ********** , which I did and got voice mail for several days in December. I called Vodacom for business and they tried the number while I was on hold and had the same problem. I deregistered and reregistered the look for me service and still no joy. I logged calls and received service ticket numbers on sms with no contact from Vodacom. Last week I received an sms saying that the reference number was now closed. I phoned Vodacom business and asked to speak to a supervisor and was put through to Sandile who assured me that he would resolve the matter and call me back. That was last week Thursday and still no word from Vodacom. Service in that past has always been great and the people great, but this has been going on for more than 3 weeks and no solution or communication. Reference number from Vodacom A2-B7GN-7UL2H2.
