Poor Service Delivery!!!

On 27/09/2015, I tried to load BIS on my Blackberry phone, but couldnt,until I decided to call Vodacom, only to be told they are experiencing problems with the loading of BIS. They sent me some settings, which didnt work. They then sent a me a message saying they are sorting out the problem, and would contact me in the next 48 hours. No call came, until 72 hours was over. then I decided to call them. Still it was not sorted out. Last week, I called again, by then i said they must pay me back my R59! They agreed, but todate i have not received it! Thism orning, i receive a stupid message from saying, saying the BIS problem has been sorted out, on the 28th Sept???, when they had sent me a message on 28/09/15, saying my problem was with the engineers! Till today, i have neither BIS, nor refund!!!
