Igloo balance dispute

stu18p

I'm interested to hear thoughts on what to do about an ongoing dispute I'm having with Barratt Smith & Brown debt recovery agents, employed to recover overdue debts on behalf of Igloo Energy who have ceased trading.
My statements included many estimated readings, when I had been supplying actual reading via the Igloo portal online. I was also sent two statements of my account on the same day, 22nd December 2021, where one said the balance was £602.74 and the other said the balance was £1,261,11. 
I have raised this via email and no satisfactory response has been forthcoming, and this morning I have received a letter threatening further action if I don't pay that claimed balance now estimated to be over £2,000.
I know that I owe Igloo a final payment, but my concern is that if I pay what they claim I owe, which simply cannot be correct, i will have to dispute it after and I don't have any confidence in their ability to bring things to an accurate conclusion.

Do you have the opening and closing meter readings? Plus the tariff rates. If the tariff has changed while you were a customer do you have a meter reading for those dates?

Use the above information to calculate what you owed them (or post the figures and somebody will do it for you).

Now add up all the payments (direct debits) you made.

Deduct the payments from the cost of energy you used and you have the amount that you owe them.

From there you can start dealing with a balance dispute, at the moment you only got the feeling they are wrong.

Thanks for the advice pochase. The problem I have is that all meter readings were submitted online via their portal and this is no longer working. They have sent me copies of my statements from August 2021 but nothing before that so I cant see the full picture. I'll have to ask for copies of all statements I think
