Telkom Nightmare

In late September 2018, i made an order for an ADSL, this order was cancelled before installation, however i had already paid the deposit required. Since October Last year, I've been struggling to get my refund back as they claim that the is a network order under my name for the ADSL Line which I do not have. I've been struggling to get the line cancelled, I've made numerous calls to no avail, spoken two different people who are supposedly supervisors who promised to follow up and get back to me, i have not heard from them to day. its it now 2019, and still this network line is still running, i have lodged numerous disputes, Ive been told that emails have been sent to idirect to cancel and nothing. i am sick and tired of running around for money owed to me. I just want my deposit back
