Bad Clieng Service

I had very bad experience with telkom, I want to cancel my contract but I’m not getting any assistance I went to the branch in Highveld mall and I was told the system is slow, but I didn’t get any confirmation whether my contract would be cancelled or not, I also called their 081180 number and the lady couldn’t assist me on the phone telling me that the system has been offline the whole day. I’m unhappy with this service because this means I’m going to keep on paying for data I don’t want and need anymore this is bad client service and I will be sure to contact ombudsman with this matter
