Oh, well. You have complained about Cell C service delivery since February last year (Full signal, no throughput!!!). So why it happened that you decided to buy very large package at first place?
I don't argue, there was no reason to shut it down. It happens.
I needed the E3276 modem, and they were the best priced at the time for the modem with data that wasnt split into silly morning/evening/afterhours blocks. I has actually been working flawlessly since I bought it, where my Cell C iPhone at the time sitting next to it didn't know what a data connection was.
