Billing errors, bad network and poor customer support.

Poor network, bad customer services and the worst billing system. Please upgrade your network and hire more professional staff to deal with customers queries. There's too much noise in the background at your call center, it sounds like a social gathering, rather than a work environment. Your call center agents need more technical training, they rely on scripts heavily and don't know how to respond to technical queries. I'm tired of having to buy data out of my own pocket, while waiting for rain to reconnect my sim.
