Poor Telkom Customer Service

I requested a payment arrangement with Telkom, I spoke to Nokthula (Telkom Agent), she explained the (40,30,30) payment arrangement, I accepted, she advised that I have to send proof of payment. I made the payment, sent her the P.O.P, she acknowledged that she received it. Lines were restored for 2 weeks only, then to my surprise it was suspended again. For the next +/- 2 weeks, I was calling going back and fourth with 5 Telkom agents, all telling me that Nokthula never logged a case, escalations after escalations, promises to be called by Team leaders and Supervisors, no calls received, I constantly had to call them back to follow-up with no one giving me a solution. Last call today spoke to Mbali, she lost her patience, she was very rude, spoke over me, she just quickly wanted to end the call. At this point I am fed up with Telkom. I want to cancel.
