Incompetency of call centre agent

3months later , I still have a bill dispute. I received an SMS saying that my account in in arrears for R2534.<br> I called to upgrade my phone, only to be told that we have no IPhones available , I will place you on a waiting list. When enquiring if my contract remains the same still the new phone is available the agent rep**** yes. Only to find a few days later my phone is hotlined and is now being billed for an open line. I was contacted by Shadarack and Blanch Opperman, who advised me that they needed to await validating of internet usage, which offcourse if placed on an open line will be billed at ridiculous amounts. I am liable for the bill since it was due to internet usage, let me remind you again for a phone that is still suppose to be on contract of R399 per month.<br> I have sent several emails and have still received no positive feedback. Why must I be the one to pay for incompetence of the call centre agent. I have been a loyal cell c customer for many years and find it absolutely upsetting now that cell c can't take responsibility for their incorrect actions.
