Cell C keeps taking my money for data and now my #

I kept buying Cell C data for my ****le as a backup for when my ADSL line is down - but I never used it all and the Cell C data kept expiring. The Cell C saleswoman suggested I spend R299 on data which wouldn't expire for a year, so I bought that. But I wanted to use my data last week when Telkom was down and it told me it had EXPIRED - before my year was up! I went in to the shop today to be told that if don't log in every 3 months Cell C simply takes my number back and I lose all the data I HAVE PAID FOR. This is *****ING! I paid for this and was told it would last a year. And I find all this out when I NEED TO USE IT and this is why I bought it in the first place.<br> <br> No one told me to log in every 3 months and how can you just close my number like that - when I still have valid data loaded on your system that I have PAID FOR and that shouldn't expire for a year? This is absolutely unacceptable and I want to be refunded or I want my data to be reactivated. <br> <br> All the shop lady said was I can pay another R299 for another year's worth of data. So you can just ***** it again Cell C????
