Cell C Marketing Product Changes (Very Underhanded 01 Oct 2017

I regularly purchase 100 & 200gb Data Bundles from Cell C (8k plus for the last few months). As of 20/09/2017, Cell C very underhandedly reduced the validity period of these bundles from 12 months to just 2 months!! The product description on all the Cell C Invoices however show following purchases as being valid for 12 Months (365 days): 24/09 100gb @ 1499.00, 26/09 Purchased 50gb ********** 02/10 ********** (new price).

The website pdf, shows that these bundles are valid for 2 months. I also confirmed this with the call centre this morning. The only reason for purchasing the these bundles is because they are valid for one year. Right now I am waiting for Cell C to confirm 1. If the 3 bundles purchased after 20/09 are valid for 365 as per invoice product description or 2. If not ... Will Cell C amend term to comply with Invoice description.
