Purchase Error

On the 18th January 2018 I incorrectly purchased 200GB of Black Data instead of normal data not knowing the limitations of the black data.

After several calls to the customer call centre as well as a mail to the Cell C customer service I was simply told there is nothing that can be done to reverse or convert my purchase to the intended product needed. I find this very hash especially due to the cost of the purchase I incurred. I have been buying large data bundles from Cell C for just over a year now and would expect proper support in a instance like this to be rectified.
