Telkom charging me even though i requested cancellation months back

FAULT *** Status :OPEN

I had logged a call to cancel my service on: 14 June 2018 around 2:30 pm and received the following in an email: Hi MR. PRIVESH BALIPERSAD. Request number for service to be cancelled ********** 659 : **********

but I have been getting statements every month. I'm am not going to pay for this as I logged the call moths back and no action was taken. I think I should contact my lawyers to resolve this
