ESA claim

Hi
Well I sent in new bank statements a month ago because my savings had changed to below the £6000. I wrote a letter showing the total of my 5 bank accounts and pointed out the benefit arrears payments which I know should be disregarded. I did all the calculations for them on this letter, made it really obvious and easy because I did not want any mistakes. Well instead of my ESA increasing they have reduced it.
Their calculations mean that my savings would have to be £9000 plus and the bank balances only totalled £7000 plus and then with benefit arrears payments, they should have used the £4000 figure I gave them which would mean no deductions due to savings. Was on the phone nearly an hour trying to get through, gave up in the end. The letter refers to MR if you disagree but surely I do not have to do that just because they are hopeless at their maths?

Hi, had a really frustrating day with ESA grrr. Phoned early this morning, goodness how I have come to hate their while you wait tune/melody. Eventually got to the front of the queue, full of mixed emotions of relief that the tune had stopped but frustration because I am trying to sort out their mistake in calculating my ESA . Supposed to get a call back from office dealing with claim my within 3 hours, it never came. I phoned back and got another 45 mins of the delightful tune, along with a promise of a call back within an hour.......which never came. I phoned back and got 55 minutes of that wretched tune and a another promise of a call back. I really want to complain, and even if I get the call back on monday I think it terrible to have to deal with all this and a MR over their mistake calculating my ESA. I just hope that the MR is done properly or I assume I' ll have to go to tribunal, all because the staff cannot do some basic calculations correctly........Is this common?

Call back never came this morning. So I phoned again at lunchtime, was told by benefits enquiries that the office dealing with my claim had realised they had calculated it wrong and had amended it. But their amended figure still wrong! The lady said she is informing her manager and made another call back request to the office dealing with my claim. Anyway the time slot for the call back has been and gone again, that's the fourth time they have not done the call back. It is appalling, Thankfully I am not heavily reliant on the ESA money right now.
