Dissapointed with Cell C service

Good day

I received 1.2 GB of data from Cell C on the day that they were experiencing issues. On the 04/12/2018 the evening i checked my data and had I had 998MB remaining.Please keep in mind that I also have an active shoutout data bundle that has about 300MB.The only applications I use is Facebook and Whatsapp,I fail to understand that from the time advised as above till now I have 36 MB remaining.

I then called Cell C customer service whom did not assist me at all. The consultant asked me the same questions over and over after I explained everything then she placed me on hold for a few minutes and then came back to tell me her system is not updated and that I should call back. I was not assisted at all.

Really dissapointed with the service received.
