Telkom is Ruining my Life!!!!

I have moved into a new property where there was already an active home phone and 2mb adsl line. I completed a change of ownership form went all the way to a telkom store to hand it in where they assured me i can ask for the same provider i had at my old property to take over, they tried and it was rejected because of a pending order, i called Telkom on Monday 1st June and waiting 40 mins before i spoke to a Human, this person then assured me for 10mins further that there was nothing preventing me from moving to another supplier, i contacted my supplier who again attempted to take over and again it was rejected for the same reason which means she did absolutely nothing, i have e-mailed escalations twice over the last few days to call me back to resolve and have heard nothing back, i called again today was on hold for 45mins and then was cut off, telkom has now sent me an invoice for R680 for being in the property for 3 days and have also cut off my adsl line... i work from home so this is having a massive effect on my income and i have literally had enough... The service i have received is nothing shy of pathetic and i will be seeking legal advice for compensation shortly...
