missing airtime

After a poor experience with a Cell C data contract some years ago, i decided to try them again for a small back-up pay as you go sim card.<br> The Pinelands store pulled records showing mostly data use as reason for lost airtime but 1 call to an unknown number for 58 minutes.<br> i don't use data much on my phone, and can't remember ever talking long on a mobile phone. Not smart.<br> So, sadly there is not much competition in SA mobile market.
