Telkom Canal Walk worst staff ever

I have been a Telkom client for more than 20 years.Telkom Canal Walk is the worst experience ever.I used to get excellent service but Nolwazi have a serious attitude problem.I have been billed incorrectly past 2 months,i reversed one debit order.I entered store at 11h57 ticket nr 12.When i approached the desk i politely asked why is there no seating for clients as i have a chronic muscle condition.Things went downhill from there.Nolwazi told me i am not interested in your job only whats on the system.I tried to show her my banking app as proof of payment,she was not interested again its the system.Asked to see manager,not available.Nolwazi printed incorrect bill,but refused to print adjusted bill system won't allow it.I was also charged additional R222.99 for debit order that i had reversed,although Telkom admitted incorrect charge i am still liable for this amount.Nolwazi kept me waiting for 30 minutes pretending to look at her screen claiming again stating i am not interested in your proof i do what the system says.I have never received such poor service and Nolwazi attitude need serious checking,she should not be employed in customer service position.I wanted to cancel my contract again she claimed i will do it immediately,but you won't have internet access as of today.I disputed this and told her i am paying a full month subscription,again to no avail its the system.Loyal client of more than 20 years and getting this kind of attitude from staff is totally unacceptable.I will not recommend Telkom to anyone due to one staff members arrogant disposition.
