7 Customer Service Agents no joy.

Loaded airtime, converted some of it to data. Logged on to the net. Airtime gets depleted before data. I call the customer service, all of them insist that they log a complaint with some other department, to which I refuse and request that I speak to the supervisor cause I needed a speedy resolution to my problem. 15 minutes later on all seven ocasions my line goes dead. None of the people that I sopke to feels. A need to call me back and assure me that they are still trying to get me in touch with one of their supervisors. Now I send cliets emails by creating a hot spot and connect to the net via wifi through my laptop. I have to wait for them from 2hour to 7days.
