Scottish Power is the worst energy supplier I have ever had. Their customer service is shocking. In the year that I was with them they messed up my smart meter installation and I was told I was £2k in debit, they then put this right after the most frustrating experience of trying to talk to someone who could help me. They then stopped billing me for electricity and were telling me I was £700 in credit, even though I was submitting monthly readings. Once again this resulted in endless call waiting. I challenged my final bill and found it almost impossible to get a sensible response. I have never left a negative review before for any organisation or service, but they are absolutely incompetent and the customer experience has been the worst I have ever had the misfortune to experience. I feel sorry for the staff, it must be soul destroying to work for an organisation that is so inept.
