No mobile network for two weeks.

So, earlier this month I had a problem with the network, being without mobile network for a week. Then after I complained here, suddenly it came right after another day. Now, I have yet again been without mobile network since the 18th of this month. So, for February I have been without mobile network for 2 weeks. But I have to pay my full bill at the end of the month??

I was told to switch roaming to Vodacom, but my phone doesn't pick up any Vodacom.

This is absolutely ridiculous pathetic.
