Cell C LTE/4G & Customer Service

I ordered a LTE/4G sim over the phone, the process was smooth, and that’s were it ended. Sim was delivered, and +R600 was take from my bank account. It’s approaching two week now I’m still not able to use my sim and I’m being passed from my department to the next and no one is able to help aid my situation. I have canceled the contract since then, they advised me that a technician would be in touch with me, till today I have not heard anything. Most agents I have dealt with have very little Customer service! Never again will I ever use this provider.
