Problem with account since April 2015

I upgraded my 2mb ADSL to 4mb in April 2015 and since then I have endless issues with my account. I asked for my line to be upgraded to a 4mb line. The sales person added a lot of extras that I did not ask for like a weekender plan and an additional adsl data package. The additional data package was resolved but I have logged account queries a few times and every time I was told that they have taken the weekender plan off my account and I will be credited. It has not happened! When I tried to cancel my ADSL line, I was told that I have a two year contract. I did not ask for it or agreed to that. I phoned the call centre to ask for the recordings of my call where they upgraded my line, I was told I cannot get it. According to the consultant at the Consumer Protection Council I am entitled to the recordings. I want the recording of that call where I was explained that it is a two year contract and where I gave permission to add the weekender plan to my line.
