Wish I could vote less than 1 star

I moved into a BRAND new home (no one had previously lived there which is something Scottish Power couldn't grasp) Sept 2015 and immediately switched suppliers. I started paying my new supplier (Extra Energy) and after 4 payments my DD stopped. I contacted Extra Energy to ask what had happened and I was told Scottish Power prevented my gas from moving (but let my electricity move?!). I contacted Scottish Power to pay what I owed in July 2016 and I am still trying to sort things out. I live alone in a 4 bedroom house and am out the house 8am until 8pm (showering at the gym) and cooking 1 meal per day and turned off all my heating as I was worried about bills (first home). They are trying to charge me an extortionate amount for my gas only - when I first received the bill they told me it was for gas AND electricity - which would have been a fair price, then it changed to gas, either way I agreed to pay it but their over the phone payment system wasn't working, when they called me back 2 days later the bill had gone up £200! This was mid January 2017. I have since sent a letter, 2 emails and asked for 2 call backs which haven't happened...how am I supposed to pay when no one contacts me?! I was also told (by someone in their call centre) they cannot bill me past 365 days (which would be Dec 2015 and prior)...2 days ago I received a bill for Sept 2015- Dec 2015...NO ONE knows what they are doing there. I spoke to one lady in the call centre who when I asked to speak to someone more senior, she informed me there was no one...apparently I was speaking to the owner of Scottish Power wow.
