Closing my landline and not my internet and charging me

<p>Sent a e- mail requesting my landline/internet to be cancelled on the 15/3/2016 . They cancelled the landline on the 1st of April 2016 but never closed the Internet facility until August 2016 . Then charged me for the additional months which I did not pay and now the lawyers are continuously hassling me for payment . Been to the Telkom store about 6 times and they log a complaint and nothing gets resolved . </p>
