MOBILE NETWORK UNAVAILABLE - NO ASSISTANCE

My mobile network has been down since 18 Dec 2015. I cannot make phone calls, send smses or access the internet. I cannot receive smses or phonecalls either. I cant phone customer service or check my balance.<br> <br> I have been to two cell c branches over the weekend to sort this out. My sim card works fine in another phone but, my sim card will not work in my phone. other sim cards do work in my phone. <br> <br> I have reported this many times but, have not received any assistance to resolve my query. I have tried doing a sim swop but, was advised that I cannot do a sim swop over weekends because I am on contract.<br> <br> I AM STILL WAITING FOR ASSISTANCE FROM CELL C. As a customer on contracted, I am disgusted with the service I am receiving. No one will help me resolve this issue. <br> <br> I am currently in credit with my account with Cell C and still I get **** service in return. I will not make another payment towards my account until this matter is resolved.<br> <br> My next step is to involve the umbudsman.<br> <br>
