Leaving paid customers in danger for no reason

My line was cut withou any notice today for non oayment after i already made payment on the 4 june while the due date is onky on the 6th. I have immediately send the proof if payment with all my details to cell c on 4 different email adresses and received a response that my email was received on all of them. Now a week after sending these emails was send and my account was fully paid they say it was not received. I tried to speak to them tonight to reconnect the acc but they say i must send the pop which i said i will immediately send to them if they just open the use of my phone but the didnt want to listen to anything. Im a lady who travelles to work inthe dark morning an evening long distance that is dangerous and now im without a phone due to cell c not attending to theie emails. This is kot the firat time they cut m line without reason they have cut my line once for 4c Worse network in south africa
