Worst experience of my life to date!!!!

My horrific experience with Telkom started when i decided to give them more business. I added WiFi to my existing contract and the Sales lady Tshepiso Baloyi at Centurion Sales added more 2 more contracts instead of 1. Before i signed i realized this and requested that she change it - she went back to the back office and came back with an updated contract showing the correct number of products on my name - i the signed it. Two weeks later i receive an invoice advising me what i will be billed month end - that when i realized that they never cancelled the erroneously added contract.Immediately I went back to the same shop that i signed up and i was turned away at the DOOR advised that they don't deal with follow up queries or billing issues they only deal with sales - i was ****ed and told that lady that you made this mistake two weeks ago and i am not billed as yet so technically the sale is incorrect - indifferently she told me to call the call center. Little did i know that "call center" was practically non- existent.My first call after numerous attempts was eventually successful - a lady advised that the Centurion shop is talking non sense - they need to fix this - so she could not help me either i advised her that i work and don't have time to be taken from pillar to post i need this sorted before the debit order date. She said she will get someone to call me before the debit date. Needless to say no one called me back and they debited me fr 3 contracts - i reversed that amount hoping that perhaps that will get someone's attention - no one called. I decided to go back to the Centurion shop and cause some noise to get some attention - when i got there i demanded to speak to the same lady under false pretense just so that they will let me see her. When i got to her gave her all my details and she checked the system and remembered our encounter and said she is surprised it was not cancelled. She told me that she will submit this to billing and loaded a case number and said she will get back to me - Again i said please sort this out before the next debit order date. Still that was not done and they kept debiting me double, triple the amounts and i kept reversing them as i could not afford such amounts as i had not agreed to them. You can imagine my account profile by now - months passed by they kept deducting ridiculous amounts of money and i kept reversing praying that someone from accounts will call me - still nothing. 5 - 6 months later i'm advised that my account has been handed over to Legal - WITHOUT EVER TALKING to me to discuss why i'm defaulting on my account?????!!! This man calls me and tells me this and then i asked will they " Legal firm" call me to then discuss a way forward then - he said yes - still to date - Nothing. This month ( November they deduct R8k from my account!!!!??? Where on eartj do they think i get that type of money and the nerve to do this without ever taking accountability of their mistake and acknowledging that im in this saga because of their lack of proper administration....I work in a financial industry and never have i seen a company that treats their client with such indifference - where is the after service?! I want someone to call me to sort this out ASAP!!!!! I regret the day i ever went to that store to add another contract........
