Impossible to cancel add-ons

27 Oct 2015 went into Wonderpark branch, requested cancellation of Standard Call Answer and IdentiCall, got order number ***A<br> 10 Dec 2015 items still appear on bill, log reference ***5, received refund of R17.24 (counts to me as acknowledgement of issue)<br> 6 Jan 2016 items still appear on bill, talk to Sales that confirms the items are now removed, get reference ***3 for dispute at billing, get no feedback where 7 to 10 days was promised<br> 6 Feb 2016 items still appear on bill.<br> Need items cancelled, please escalate to Sales Executive.<br> I further understand that IdentiCall was included in the base line fee of R189 incl VAT from a certain date. I thus need to be refunded for that over payment as well.
