WORST CUSTOMER SERVICE EVER!!!!!!!

after multiple calls to call center i got through to the network department. where the agent said the network tower is overloaded and they cant do anything for me. when i asked for proirity to stay connected because this problem is effecting my work the person just said no. i phone now again to ask if someone else can assist me to perhaps grant me proirity and then i found out that the resolved and closed the call on the system without resolving my problem. i now need to log a new call as they cant re-open the call they closed that is not resolved.
