Shocking service

I canceled my line with Telkom in May 2018 and only in Feb 2019 i hear it has been cancelled but i owe you amounts even though i was told in June 2018 it was cancelled and correct. I then sorted this mess out and requested a settlement letter to stop this happening again. For the last five days i have been asking for this letter to which i have received nothing. i Have never known such an *********** and painfully useless company ever. Your service is beyond terrible along with the total lake of customer concern. Your staff are unwilling to help and couldn't care less about anyone's problems. I would never recommended Telkom to anyone for anything ever.
