Cell C Poor Customer Relations.

During September 2021 we bought a Cell C Home connecta prepaid LTE starter pack as backup for our wifi. Before we bought we checked their website as it showed that the data will roll over for additional 30 days. We received good service and after the initial 30 days the data rolled over automatically. At the end of October 2021 we topped up the account and it went smoothly untill 25 November 2021 when about 3.6gb just dissapeared. My husband called customer service and Cell C said that we did not apply for a roll over. The person said that the rules had changed and so my data is gone. We were not notified about this change and learnt that you must pay a fee when you apply for a roll over and they would not tell me how much this fee would be and said that we will see when we apply. This is not a lot of data that is lost but surely they should inform customers about changes in their rules that cost us money.
