Account still not canceld after a month

Account & all services was requested to be canceled due to poor service delivery in my area. Accounts department informed me that a months notice was needed to which I agreed & also made the final payment.<br> <br> 2 Weeks later I double checked because it's telkom after all & the invoice was still there, unpaid. Phoned again & spoke to Tim who said the system was slow & he could see the payment & cancellation of services told me to use this *** if there was any issues.<br> <br> Found out a week later (28.04.2015) the there was no notice put through to cancel my telkom account & related services. Also received a an invoice via email last night for new outstanding amount...<br> <br>
