Extra charges

This time I am fed up with this cellC contract!<br> On their adverts they put lesser amount but when coming to debit they debit doubke the amount!<br> I hate being ****** like this!<br> From the R340 to R500.<br> I tried to call cellC and they told me that my account has and extra R400 to use whe I run out of data or minutes. I understood and told them to cancel and they said they will cancel and leave extra R50 to use to keep the account active but this month it is worse. R340 to R709.<br> This is robbing.<br> I don't advise anyone to take cellC contract and also myself I think it's my 1st and last time taking a cellC contract!
