Credit record downgraded because Telkom took 10 months to cancel line

10 months later I am still dealing with the repercussions of previously having had a Telkom account. Instructions to cancel my line were first sent in June 2017. The line is now cancelled (as of April 2018 - 10 months later - after countless of hours on the phone following up on Telkom employees not doing there jobs). However, my credit record still shows I owe Telkom R5000 in unpaid debt and I was flagged as high risk because of this. I previously reported my issues on Hellopeter, and Telkom's social media team responded, but it was all for show and nothing was ever done. Avoid Telkom at all costs!
