We used to have a normal 56k account with Mweb, but it was horribly slow.
That prompted my mom to get an ADSL account. Not sure why my mom went with a 1024 one nor did I know there were any other line options available for ADSL till now.
In November & December last year we had the very same problem where our cap for the month would finish in 1-2 days. Which left us pretty confused as I'm usually at university & my mom doesn't know how to do anything else but check her emails.
When we spoke to Telkom about it we were just told to get two extra 3GB additional caps which we did. In January this year we decided to cancel the accounts since we hardly used them.
When we tried cancelling them, every month our account would show the additional caps as STILL being there. So on 31 March I decided to phone Telkom again. I ended up speaking to someone who told me that our ID number for the account was mixed up so the account therefore was not being cancelled.
At the moment I'm waiting to be credited on that. Well I hope to be.
