Poor communication, unprofessional

Useless useless service I have ever experienced, beginning of last year I wanted to cancel my data contract sim card cause I was complaining of network and they told me I can only cancel it in October last year I told them to make sure they do so in that October because it is such a mission to get hold of them, till today they are still taking money from my account and 3 months now reversing all the time ,when I call the call centre around 7am they say consultants start at 8am, in me reversing the money no one at Telkom has ever called me to find out why I'm I reversing the funds ,and the amount they are taking keeps going up, don't even use that sim card anymore nor I know we're it is, surely wen someone is reversing moni as a company you will call to find out reson for doing so, WILL MAKE SURE EVERYONE CLOSE TO ME KNOWS THE KIND OF BUSINESS YOU RAN.
