***They don't even deserve one star - but I had no choice but to leave one*** STRONGLY ADVISE NEVER TO USE SPARK ENERGY - PLEASE READ BELOW: I moved into my flat in Nov 2018 at which point I provided my metre readings to date (as did the previous owner) they are still telling me they are running off estimated metre readings after making numerous phone calls to provide them at which point I was advised that I have an outstanding debt amount and that they expect customers to call once every month to provide metre readings. (Please bare in mind every time I call I'm on hold for 45 minutes to 1 hours before I speak with anyone) I live in a studio flat (which is one big room with a kitchen and bathroom attached) I was originally advised when setting up with spark that it should cost £35 per month, this was the agreed direct debt amount. After 2 months I noticed the direct debt amount went up to £250.00 per month. Currently I have turned my central heating off at the mains and wash up with cold water because I can't afford this amount per month. I have had to cancel my direct debt with Spark as the last payment they took was for my mortgage payment, given the global pandemic the last thing I personally need on top of everything else I'm trying to manage I DO NOT NEED TO DEFAULT ON MY MORTGAGE PAYMENTS BECAUSE OF SOME BACK STREET COWBOY COMPANY. I have received a letter advising I'm now in outstanding debt of £570.16....... I have tried to change over providers as other companies have advised me this is disgusting! Spark allow the change over until the day before it is due to happen and then reject it. I'm now receiving debt collection letters threating legal action. Everyone I have spoken to has been disgusting! I'd be surprised if any of the staff members undergo any form of training. I am seeking legal advise at additional costs as well as including 3rd parties. Maybe now they will be a little bit more inclined to listen. I'm a single person living alone, my mother lives in a 3 bedroom detached house and is costing her £160 per month for gas and electric! If this matter isn't resolved soon I am genuinely scared for my life at this time. I hope things do not have to go to this extreme before someone will listen and take action.
