Cannot connect to BIS

Hi. I loaded BIS on Tuesday and still cannot use the service. I called the call centre on Tuesday. The consultant mentioned it would be resolved within 24- 48 hours however it's not. It's 3 days now and it's beyond frustrating. Not happy with this service. I have mentioned this to the Vodacom support on twitter - however I have not been provided with an indication on when this issue will be sorted. <br> Please assist as this is very bad service.
