Telkom Won't Close My Account

I went into Menlyn's Telkom branch on 11 March 2015 to discontinue my account as I moved. I then paid my account for a bill I received up to the 3rd of April 2015 as I was told the notice period is 30 days.<br> <br> I then received a bill from Telkom for 4 April to 3 May, and I went to the Menlyn Telkom store to confirm the cancellation again - with my reference number for the cancellation. I received an SMS stating that Telkom is sad to see me go, blah, blah, blah...<br> <br> Yesterday, 6 May 2015, I received yet another bill from Telkom, for services from 4 May to 3 June. Added to the previous bill, putting my total due at R1216.<br> <br> I should only be billed for 4 April to 11 April, after which this account should be closed. But Telkom cannot seem to understand or manage that....
