Scottish Power's customer service (Cough)

My response to Scottish Powers 2 letters they sent me and 15 minutes on the phone without speaking to a human being. To whom it may or may not concern, How diabolical is your customer service when I phone and in 15 minutes I didn’t get to speak to anyone. I called at 5.15pm and stayed on the phone for exactly 15 minutes. I know you will have the excuse that I called at a busy time, but that is when I finish work and when I wanted to call. If you know that is a busy time then I suggest you hire more staff, as you know people are begging for jobs and I’m sure they would jump at the chance to work for a company such as yours. So as no one bothered to pick up the phone I now have to waste more of my time emailing you. i couldn’t stay on the phone any longer as you are aware I am already in debt with yourselves and don’t intend to be in debt with my phone company. Thank you for adding to my troubles. I have a full time job and a child and like pretty much everyone else in this country I am struggling, so I don’t appreciate being sent an amended bill dated 24th September 2013 then a threatening final demand dated 25th September 2013, which both arrived on the same day. I am not psychic (if I was then I probably wouldn’t be in debt.) How was I to know what the amended amount on my bill was? I suggest you check your system and amend your computer generated letters to give people a chance to respond before demanding I “pay straight away to avoid collection charges being added...” on the same day. Please could you explain my bill to me as there is an account adjustment and it states my account balance on the 30th August 2013 is £120.16 for charges for last period then, on charges this period the account balance total is £192.71. The bill period is from 14th June 2013 to the 31st August 2013. How have I incurred a charge of £72.55 on one day (31st August 2013) when I was not even living at the property at that time? I will not be wasting any more of my time trying to call so I suggest you call me on 01903 ****** after 6pm or email me back to this address. Please note that I have made the effort in trying to contact you and any more threatening letters will be looked at as harassment and dealt with accordingly. I will be waiting for your ever swift response.
