DISGUSTING, PATHETIC, ***********, WORST SERVICE EVER!!!!!!!

I have had a number of encounters with Telkom, ranging from them taking more than the turn around time give to resolve queries, to no responses to escalations, the list is endless. The most recent encounter is an invoice I received amounting to R1400. The amount unknown to me is an amount of R500 on the invoice with the reference "data usage". I called in to their useless call centre to enquire about this, and spent a total of 45 min on the phone with the consultant trying to resolve my query. He tells me that the amount is for my wifi modem deal (which by the way costs R99 for a 5gig wifi modem) He tells me I had depleted the amount allocated to me and as a result went and used Telkom's data which they are now billing me for. ALl good and well, however, I DIDNT ASK for an additional amount to be allocated to me should the 5 gig be depleted, secondly, on two occasions I have called in to telkom asking that the put a limit of R0 as an additional spending limit on all my lines with them, meaning I don't want to pay for anything extra that is not a part of the deal I have taken up. SO I don't understand how this cam to be that an additional R500 is now added to my invoice amount. I asked to speak to a team leader and the guy would not put me through, he kept putting me on hold and eventually cut the line. I called again and spoke to a different person who also kept putting me on hold citing "system problems". Needless to say I am still sitting with an unresolved query and no body is willing to assist me. I regret the day I ever made any deal with TElkom an will NEVER recommend anybody take up anything with them.
