Slow response and feedback on technical issues

I have been phoning each day, for the past two week, for an update on when our satellite internet issue will be resolved. Each time I get the same answer, that the on-site team will call me back. I am still waiting for feedback. Our business depends on this sole sources of connectivity and will have to start looking into other ISP's if this cannot be resolved. The lack of communication is extremely unprofessional for "A Leading South African ICT and Telecoms Operator".
