Fails to respond adequately or resolve issue

This is an ongoing issue that has not been resolved and I have not been anywhere near reasonably accommodated. I purchased R150.00 airtime for my Cell C USB modem and converted it to 1GB data. Received notice via sms to the Cell C modem app that I had received the data and 400MB 'free data'. Within an hour the data was depleted and I had only been working on emails and limited use of social media. Despite numerous emails to the customer service email explaining that I am not able to hear on the phone and would like to have my query attended to in writing, I am still receiving emails saying that I must phone the customer service. There is no consideration or even notice of reasonably accommodating a person who is not able to hear on the phone.<br> <br> I have the proof of purchase from my bank and the pdf. acknowledging the purchase from the myCell C website.<br> <br> In over a month Cell C have not been able to respond adequately or resolve my issue.
