Cancelled Service in Feb'16 & Still being billed today Jun'16

<p>I cancelled my service in Feb '16 & forwarded a letter as well. I am still being billed today. Telkom has adopted a "dont care" attitude towards their business clientele and it is showing drastically. This is ridiculous as i have the proof of cancellation as well as the emails sent to them since feb'16...BUT the statements keep coming!!!</p>
