APPALLING SERVICE AT CELL C

No one from Cell C is responding to my complaint, they just acknowledge and tell you they will come back to me. I cancelled my contract with them but they say I owe them when I call , they tell me that I don’t have a contract with but they won’t remove my name from ITC , are guys even serious about service???????? Nthabiseng Uhutu, you promised that you this will be sorted and nothing as yet since March ??????????????
