Worst company ever, I left Scottish power since last year in April, I was a prepayment customer, but I ended up owing them, I agreed to pay the balance by installment, the last payment we agreed was supposed to be on the 28 June, and on the 23rd they sent my details to the debt collection company, when I phoned them on the 29th to pay the last remaining balance, the amount changed, I was told I've been charged an additional £28, which I was unaware of, I told them that we agreed that I have to pay on the 28th, I told them again, because they record call, if they can recall the last conversation I had with the agent to see what we agreed to, but they are refusing, as they know they are wrong, I regret being a Scottish power customer for all this years, ❌❌❌EXTREMELY UNPROFESSIONAL STAFF❌❌, ⛔⛔⛔⛔STAY AWAY FROM THE SCOTTISH POWER⛔⛔⛔⛔
