Suspicious business practices, dishonest and somewhat impolite customer service

I’m using the Cell C Home Connecta data package for my home WiFi, for which I have been buying airtime that I would thereafter convert to data. This has been working well for the last 4 months or so. Today I found myself unable to convert airtime to my desired data package, with the Cell C app instead prompting me to use my credit card for the transaction. When I called Cell C customer care, the agent I spoke to informed me that they were instructed (by management?) to let customers know that ever since “those bundles” were introduced customers needed to use their credit cards to buy them, which is both suspicious and untrue in my case until today. I asked her why Cell C would want to have my credit card info as a prepaid client. She did not know. I asked if she would refund my airtime (which was now useless for the intended purpose)…she said she could not and dropped the call before I respond.

Interestingly enough, the dropped call took me to the system for rating their service from 0 - 10.
