Cancellation of the service

Good day<br> <br> I've been provided telkom land line and internet for 6 years and I have left SA last month.<br> However, I recently have heard that the service is still provided although I have requested to cancel the service before I left SA.<br> Please cancel the service and DO NOT SEND ME BILLING any more. <br> I have left SA in 15th of Dec 2015.<br> <br> my land line number was ***<br> and address is 27 Somerset Place, Derrick Drive.<br> <br> Regards<br> Lim
