Dreadful customer service and service delivery from Cell C

I purchased a 100 gig data bundle on their website almost 2 weeks ago. This cost me R1600. The money went off my account, however the data is still not reflecting. I have contacted Cell C numerous times since this, to no avail. The vague response is that technicians are working on the problem. My issue is that firstly, no one from Cell C has thought to check in once in the last two weeks to assure me of the progress. Secondly, The bundle cost a lot of money and since I do not have the data (which I use for my phone and laptop), I have already used over R300 in airtime and data bundles as a result. Thirdly, even if I wanted to try and reverse the transaction: it takes 7 to 10 working days to reverse apparently. I find the service that I have received quite terrible, and regret having been a loyal customer of Cell C for years.
