Cancellation of my adsl line

Called into Telkom to ask how I go about cancelling some services advised to complete a cancellation form done so emailed through on 3/01/2018 knowing this takes up to 30 days. A couple of days later my husband said there was a message on his cell regarding cancelling services then a couple of days later I get an email as well so I called in and was advised that I should call after the 30 days and that telkom definitely have my cancellation form if they are trying to get hold of me. So I phone in on 5/02/2018 only to be told that the service is not cancelled and I must email the person that is trying to get hold of me sent So far 3 emails no response so now I need to pay for an extra month and it sounds like the department does not know what to say and why can nobody assist me telephonically seen that my form was received paying now for 2 service providers is just not on. ????
