Product inconsistency and lack of information for decision making that shortchanges customer

I went on the CellC website which clearly advertises the 365 days data bundles and there is a link to go ahead and purchase this on the website. I identified what I wanted: R899 for 30G for 365 days. On Sat 12th Jan I went on my FNB App and came across the deal I wanted: 30Gigs for 899. I went ahead and purchased this. To my surprise I get an sms report of my purchase and the data is valid for 90 days (12 April 2019). So basically cell c has the same product for the same amount with different terms (imagine the difference between 365 days vs. 90 days) depending on what platform you buy it from; which alone is already infuriating to me, the customer. Even more annoying, there is no information before purchase to tell you that this particular bundle is valid for 90days, and ofcourse I made a reasonable assumption that I am buying the same product that I saw on the cell C website! How am I supposed to know that this one bought through this particular platform lasts for only 90 days?

What has been a complete nightmare is the contact centre, giving me the run around since Saturday; 1. They can not solve my issue so they escalate it 2. The backoffice they escalated to sends me an sms that says absolutely nothing and in fact shows a lack of knowledge of their own products! ...and of course I can't talk to them directly so I have to go through the call centre again for them to ask their back office to call me back (almost 10 calls and still counting). The call centre does not even have means other than email, to contact the back office apparently. So I just have to wait until someone decides to call me back. 3. I have demanded a refund of my R899 and a reversal of this 30G data yesterday morning. I sent an email with proof of purchase as advised by the call centre and still no response more than 36hrs later. In the mean time I have been advised not to use data on my phone if I want a refund...So i must just wait (from Saturday) until someone in the back office decides to call me back or respond to my email refund request. I am completely at the mercy of their inefficient processes, product inconsistency and lack of adequate information before the customer makes a purchase; meanwhile they have my R899. BTW, why is data still expiring again? Annoyingly, Cell C is the one that went to court to block the timing of the implementation of the ICASA recommendation on expiry of data among other things. Go figure!
