Disgusting Telkom call centre service

Utterly disgusting and dissapointing. I have been an Operation Manager in the call centre business for 6 years. I called in on sunday 26 Aug 2018 to ask why my line was not reconnect after payment was made Friday, the first gentleman by the name of Donny said he could see my payment and would send a manual request of to reconnections. I was ok with that....4 hours later I called in again with the same query...the african lady then told me she could not see my payment and no record of me calling in on that sunday. I was irate and wanted to speak to a supervisor as I use my wifi for work purposes. She said she will spoke to her supervisor and will put me through....guess what....30 mins later im still on hold with no Wifi. My guess she never spoke to a supervisor and simply just put me on hold. Terrible and disgusting services. When the telkom actual service works i have no problems but ur call centre customer service staff is very ill mannered with no concept of what customer service is. I am still on hold apparently through to a supervisor. I would like to take this matter further. Can anyone advise on the next step?
