Telkom billing incorrect after sales team calls to upgrade your service
Telkom sales contacted 6 months back saying that they going to upgrade my uncapped line from 100mbps to 250mbps line with the same cost Im currently paying. They reassured me that its a promotion and I will be getting faster line at the same cost Im currently paying. 
The next month my bill was 400 more than what I use to pay and on contacting them I got no resolution to date. Numerous calls logged and requested to calls sales and then billing and back to sales.  Im currently paying upto R1000 more with telkom that what I was paying with no resolution. When calling billing they dont give you reference and say they escalating with sales team and cannot provide reference and the sales team does the same, spoke to samantha who said I should call billing today. 
I managed to get a few calls logged when I went into the telkom store but the issue never got resolved.
Today I spoke to nothemba ncapayi and she refuse to give me a reference and when asking to speak to the team lead she cut the call.
Some of the reference I logged with telkom for this issue.
