Lie, after lie. Promise, after promise

On the 15 May, I called to upgrade my 20gb sim only contract to 40gb. I spoke to Phumele Nkosi who processed my order. Phumelele confirmed with me that I would be receiving a free wifi router (great, although I didn't ask for it), and that my upgrade was effective as of the 16th and that I would receive pro-rata data to tie me over until the new month at which point the 40gb would kick in (WOOHOO!!).5 days later, I found that the data had not been loaded (and at this point I was paying per mb) as my old contract limit had expired. I called in again and was told that an admin guy would call to change the start date of the upgrade as it was still reflecting a start of the 1 June. I didn't receive a call from that dept, so decided to call in. I was transferred to Phumemele who apologized for the confusion and that she would speak to her manager to remove the money I had gone over and also load 2gb until the end of the month (this is now on the 24th Thursday). I have been without data and unable to make calls or send sms's for THE PAST WEEK and must rely on my company's wifi. I AM DEEPLY DISAPPOINTED AND ANGRY AT THE LEVEL OF SERVICE I HAVE RECEIVED!!! Especially after telling all my friends and family that I have had no issue with CellC and even recommended that they switch.
