CABLE DEPT

I've had the worst service ever, I've been trying to get feedback as my case is with the cabling dept, I've called every day for the past week and today the call centre agent drops the call in my ear. They advised that they escalated the issue called the next day to find out it was never escalated. All they can tell me is that the cable dept will place notes on the account when they do. It's been almost 4 weeks in total since I app**** for this land line. I sent emails to open serve, sent messages on Twitter sent inmail via LinkedIn to sipho and no one has been able to assist me. I need this resolved asap
