Truly awful and very upsetting. I first had issues with SP a few months ago when I suddenly went into my overdraft on my current account. When I checked this was because SP had suddenly changed my DD from about £65 to £444 and had taken 2 payments so I was £888 down. I called them and sorted this although it took me 7 calls where each person gave me different response. Readings were given and my DD went back to normal. Then in August they suddenly took £308 and in September £338. Once agin I called and this was sorted. I was put on a fixed rate until 2021 at £66 pm. Now I check my online account. My September bill was estimated at £230 so after I laid my £66 the account shows I am in debit by £163.99. How can this be when I am on a fixed rate? So when I hit the Direct Debit tab in the online account is says my recommended monthly DD should be £381.... for a 3 bed semi with only myself and my daughter?? Rant over. I’m in the process of switching
