Cell C agents give wrong info which disadvantages cust.

I purchased Cell C min on 16/8/21 for R240 and I was told it will expire after 30days. After I made a call to cell c number on 26/08, I rec sms saying to any network my min <7. This has been stressing and it baffled me. I was in hospital for 2 weeks and to be stressed more as I did not use the 240min is not fair. I queried this 26/8 with 140 and told it expired on 22/08/21. So it meant I was using my any net minutes these few days thinking I was using cell to cell C. So wrong info I was given. Agent should know their products. It has cost me to buy airtime on my other whereas I was misinformed and ****** of my minutes. It is cell c faut not mine.
