Cannot cancel contract, wrong contracts, wrong billing , unhelpful

I app**** for a fibre service to my new home in randburg on the 11th of january and at the same time wanted to cancel my current adsl in centurion. I went into the store in fourways and wa sat with a lady named Mulalo that it was done and I would recieve a call from a technician during the next few days to say that they would be coming to install. I waited a few weeks and eventually went back into the store , spoke to Mulalo again and her manager and was assured that the technician would be there the next day. I was called the day after and the installer phoned me to tell me he was going to install an adsl line. I enquired as to why adsl and not fibre like I had asked and was told I would need to contact telkom. I contacted Simxabisile at the call centre and they said I would need to apply again for a fibre line as the adsl line was what they had on the list( the comment was that I should have allowed the technician to put in an adsl and the deal was no longer available -this I then had to dispute with a senior and was allowed my original deal) . At the same time i was told that my other account was still active and I would need to speak to cancellations to get that done. I did this and was told what form to fill out and what information to put on there. the fibre line was installed. I checked up on the cancellation and it wasnt done. I went into the store again and was told to call telkom. I spoke to sibongiseni and was asked to mail documents through-which was checked and told it would be sorted out . On the 18th february I had to again follow up and Simon assured me it was done . This was not the case and again I spoke to various other agents (hlaudi, ********** and had the same experience. Today 24 may 2018 after seeing that theres a number of " services on my account which means I'm being billed 1400 instead of 450 rand each month since my original cancellations etc I called Telkom. I was asked to send the documents again and told no these are wrong ( which is odd because I was told what to fill in each time and also it was filled in twice by fourways store) . I was eventually told to log into the old portal and cancel there-I explained that I had no idea what service was what as there was T and B etc number all over. I was also told I would only be able to dispute all the money which In my opinion was ****** from me after the services were cancelled. I spoke to Roxanne Luzaan Saalmans and her senior Wayne- who did try help but the attitude since I started this whole process was " its your problem" and I have not received one apology from either the store nor anyone representing telkom with the its up to me to claim the money back and good luck with that
