Pathetic customer service

Terrible customer service, agents don't know what is going on been trying for 3 weeks to have a line installed technician came out installed the box requested for the maintenance guy to come and add a line from the other side, he came said there was not enough cable and disappeared requested for the installer to come but just to be told there was enough for the guy to do his job and sometimes if they don't want to work they do that. The laziness of the maintenance guy not even bothering to go and check the ceiling for the extra cable has costed me more time in this line being installed. When trying to contact the customer service unfortunately we get told that they also don't know, what kind of customer service is this. You train people to tell the customers that they don't know or do you train them to go the extra mile and figure out what's wrong.
