I was with Scottish Power until recently. Things took a rather steep nose dive from about last year - I could phone them up and be on hold for the best part of an hour before I spoke to anybody. Sometimes, just when I thought I'd got through to someone, they would could me off before either of us said anything - meaning I had to phone and wait again.
My best advice with Scottish Power is don't take no for an answer. If you ask to raise a complaint, they'll tell you somebody will get back to you soon, but what they don't tell you is that their definition of "soon" is about a week! Demand they put you through to somebody straight away in the complaints team - they tried to fob me off with the old "we'll try for 5-10 minutes" knowing full well the complaints queue was much higher than that. But persist and they'll sometimes wait until somebody in the complaints team finishes their tea break.
I found that once you'd raised a complaint, Scottish Powers phone system actually put me through to the complaints team without even telling me - sometimes I wasn't sure if I was through to customer services or complaints until I'd asked. Just like any company, hit them where it hurts - demand to be compensated for your stress and time.
Try Ovo.
First Utility FTW, excellent in every way. Variable direct debit so you only pay what you have actually used instead of paying fixed amounts each month which is usually more than you need to pay and they can cash in on millions of pounds held in their accounts gaining interest. With First Utility you get an email once a month asking you to submit a meter reading online and no paper bills, no hassle, online account etc. They also guarantee to always be cheaper than the big six energy companies.
Best move I ever made.
Edit - Some areas they now supply smart meters that auto send your readings.
I'm looking forward to moving to them, annoying how the switchover takes over 4 weeks! Four more weeks of paying Npower their ridiculous standing charges
I considered these but far too many complaints https://www.trustpilot.co.uk/review/www.first-utility.com just do a search for First Utility ReviewsI am about to leave Npower to go to First Utility, mostly due to CS..

I am about to leave Npower to go to First Utility, mostly due to CS. I was in quite a lot of credit and they ignored requests to change my DD amount or refund me until I logged a complaint. They would also try and up my DD amount significantly despite being in a lot of credit and with up to date readings.
In saying that their complaints department were superb, shame they didn't work in their main CS area.
I moved to OVO recently from SSE, so much better service and prices that I feel are more acceptable.
