Deeply frustrated that repeated attempts get responses that do not work

I cannot make calls on my phone. I am very disppointed in Cell-C service and in your very bad responses. I sent you an emergency message to no avail. I inserted a MTN sim in my phone and it worked perfectly. So the problem about connectivity is on YOUR side. It has NOTHING to do with my phone. You send me flippant responses despite my emergency situation.THERE IS SOMEATHING WRONG WITH YOUY SERVIDSE HERE in GOURISTZSMOND. Why ccant you get an expert to contact me. ***. I CANNOT mske or receive phone calls. You tell me i am out of artime whiilst I have good credit on this number. It is now the SECOND day I am without my phone.
