I have had previous problems with Scottish power, they were getting mixed up between my account and another account which was in debt. I have just moved house and ends up new house is with Scottish Power and have to pay them the period of time until my switch went through, asked them to send me an invoice so can pay at pay point they refused, was on the line with them for 30 mins and lady said the only way to pay is over the phone or online, went on their website and banking details was listed, they were just making things difficult for me. Customer service are a nightmare they have no idea what they are doing.
