Horrible network provider

Called through on Sunday night for a sim swop i was told they cannot assist me, because of no usage for 60 days, how can i use a sim card that's faulty.

I called the call center not only once over the past 3 months for assistance i was given different info every time i called in. I went to the store failed to assist, called the call center for the last time hoping that they will assist. I spoke to one very rude team leader that told me so much ******* and very rude. i was told he will send me my ref number for the call via sms to date i have not received anything its 2 days later no call from his manager after requesting for the call to be listened to and proved feedback on how the TEAM LEADER dealt with my query, a whole TEAM LEADER setting expectations that was not met. I requested for a cancellation amount which he did provide, and told me that the cancellations dept will contact me and give me an expect quote none of this happened CELL C customer service is the terrible. I want to cancel my contract and stay as far away from them as possible. What happened to good customer service.
