More than 6 weeks with no action/resolution

I've had a fault on my line for more than 6 weeks. After logging the fault I was given the run around for 2 weeks until a tech called me to ask if I'll be home the next day, I advised that I would be and waited all day (taking a day off work) only to find out that he closed my fault without fixing the issue. I escalated this to the call center, where I was assured that a manager would call me back. this never happened. I then reached out to them via twitter and got over 20 canned responses assuring me that the issue was forwarded to the tech team and feedback would follow. Feedback never followed. I'm convinced that the \social media team"is nothing more than an automated response program"
