AGAIN SIGNAL PROBLEM

From Thursday 15 November 2018 up until Saturday 17 November 2018 we had no LTE signal at all. We can not do anything on our phones not even making calls as while you still on the phone the call drops. I called the customer care center and they said to put our phones on roaming and either use Vodacom or MTN to roam on. This did not work at all. They lodge a complain with the technical apart and yesterday a guy phoned me to ask me if the signal was working. I said yes just to not realise that later the day we will not have signal again. Now again as from yesterday 19 November 2018 no signal again. Tried the network select but this does not work. Tried Roaming and this is also not working. In the past few weeks we were more offline with no signal that online with signal. This is pathetic service as some of us use our phones for work and now we are losing money because of the no signal. How long is this going to go on? All other networks is up and running but Cell C is always off or has a signal problem. I come to think that I made a huge mistake to Port my number to Cell C
