PATHETIC!! STILL CANNOT FIX MY PROBLEM!!

So last Friday I have no network coverage, rendering my phone useless. This leads to me being stranded at a Gautrain station, unable to contact anyone, so I couldn't get to work. After the 4th time of being transferred to Cell C's technical department (I could only dial customer care) I was told YET AGAIN that they don't know what the problem is. So after 3 days of having no coverage, my signal miraculously returns this morning for a brief moment before disappearing AGAIN. Still, Cell C have NO IDEA what the problem is. However, funny thing is i had this exact problem in early 2015, and I was left phoneless for TWO WEEKS after PLEADING for a loan phone of some sorts, but alas, was met with \sorry we can't help\". Now it is happening again. I am going on FOUR days with NO phone, and Cell C are doing NOTHING about it!!! I NEED A PHONE!!! How is it possible that a repeated problem can still not have a solution?! I pay Cell C a substantial amount of money every month for TWO contracts yet THIS is the service I receive?? I want a solution and A LOAN PHONE TODAY!!! THIS IS TOTALLY UNNACCEPTABLE!!! "
