Worst energy supplier i have ever seen before..Think 100 times before you join ScottishPower.. This company made me pay nearly half of my monthly salary more than £500 when i said i want to leave your company...it is so hard to earn that money and they will take it in jus a seconds saying that i used more electricity and gas.. totally rubbish i mean who will use that amount of energy in a month. They said i have to pay over £500 as a last bill...i was paying correct amount till june and at july i had to pay £515.24...which is a very big amount for a gas and electricity bill.. remember money is not everything in life but learn to keep your customers happy give them good service this is what an established company should be doing..at that time when i got ph call from ScottishPower they said i will be paying £67.67 monthly and now £515.24 this is definitely not a good service...this is why your customers are so much disappointed...at last learn to respect your customers and they will give you the same......
