Poor handling of cancelation

The contract dept, on 1 August 25 I requested data contract of 100G for R229 and called the next day to cancel soon as I realized that it doesn't cover data sharing. I was told is canceled. On 31 I received a quote which needed me to sign and send back I didn't instead I called in to cancel and requested the line to be on Redglex zero but on the 1st Sept the line seems to have active data activated.

Poor handling of cancelation.
