Cancelled my account

Hi <br> I've been trying forever to get through to the call centre number 10210 to cancel my line and data package with Telkom, I eventually went to there Southgate branch to cancel, I waited in the queue and was told I needed my original ID to cancel, I went back the following day to cancel the services, Lindi Khumalo told me I need to give them 30 days notice which I did she cancelled it for me on the 12 February 2015 and gave me a ref number three months later and I'm still getting billed please resolve my issue, in the mean time I'm asking the bank to reverse this months payment and I want a credit for last month.<br> ***<br> Acc. No.:***<br> Regards <br> Sean
