Overcharge for services/ incorrect cancellation

We tried to increase our internet and were told that we did qualify to have a 10 meg line. I tried to upgrade & the first consultant said we did not need to sign on for another 24 month contract. Month to month was fine. I called back & the second consultant automatically tried to set me up for a 24 month contract. I had to tell him at the end of the call that I ONLY WANT MONTH TO MONTH. Finally sorted-longer wait period than consultant stated. <br> <br> Our internet was running really poorly. We kept calling to get our line reset. Eventually over a weekend we got hold of a technition who said that we had been down graded to a 4 meg line as we were too far from the exchange. (We had confirmed with them before starting the process that we could actually get a 10 meg line). OUR PACKAGE HAD NOT BEEN ADJUSTED DOWN- they charged us for the 10 meg line for 2 months.Our line had been running on a good day at 2 megs, often at 0.8 megs. We decided to try and change our package to a 2meg uncapped. Then we changed providers. <br> <br> On cancellation of data and ADSL line my phone line was cut too. Numerous emails and promises later and my phone is still cut. I want my phone line to be reconnected
