Unhappy tenant

I am extremely dissatisfied with the service from this property management company. My electricity was abruptly cut off despite my *** being fully paid and holding a positive balance, as I consistently pay my rent before receiving my monthly statement. Currently, my *** is blocked, preventing me from purchasing electricity. Even after sending the building manager a statement proving I have a credit on my ***, I was still asked to provide additional proof of payment and told to call the office when I expressed my frustration. I need an explanation as to why my *** is blocked when my payments are up to date, and why my power is repeatedly shut off, forcing me to continually request the manager to restore it.
