Is following up really hard for Discovery??

My car's window on the boot was damaged on Monday afternoon around 2:30, I called Discovery to report this matter immediately. Musa was handled this matter, he found a company who will fit the glass for me but wasn't following up. I called Musa twice (left a message) but no one called me back, my window is still not repaired and I can't drive to work because of that. It's been a week now, Discovery never followed up this matter, I was the one who called around. I thought Discovery cared about their customer, now I need to think about it.
