Could-not-care-less customer service agent

To say I am extremely disappointed and angry with Cell C, is an understatement...

I have never spoken to such an arrogant and unwilling customer service agent in all my life...

I followed up on a reference number when I called. She was so unhelpful. In her continous response, she was insinuating that I was talking nonsens. That what I was saying could not be true as there was no evidence on their system to prove that what I was saying, was in fact a possibility. My query is related to 2 bundle roll-over requests that did not happen on Cell C's side.

My queries have not been resolved as per the previous 2 calls I received, promising to be resolved by a certain date, hench the reason for calling customer services on 135.

The number my query relates to: ***.

Truly unprofessional!!!
