Deductions to benefits adding up to over £9000

I felt like due to my mental health I have been took advantage of  with my esa claim from day 1 and also been  mocked in my pip assessment report and everything said unit was the total opposite of what was spoken and discussed totally back to front and was not given points properly  which  I should have been awarded and when I appealed my new diagnosis were not took into account and was not given anymore points for my ptsd or my copd and it just depressed me  further so just let dwp win yet again and left me so

Hi sorry I'm only just getting  back to you  I'm on income related esa with support group and should have been on £260 a fortnight but from start I have only got like £225 a fortnight so have been deducted minimum of £25 to £35 a fortnight from like 2017 and  I was awarded pip 2 years ago it's till March this year I'm sure I was getting around £420 every 4 weeks pip payment but say into my 3rd pip payment it dropped to £380 4 weekly so I  then got a letter off two this being the now 3rd letter over the last10 years saying I  I still owe a£2.500 overpayment that will not stop being deducted till 2028 and my mate told me I cut be deducted off both payments so phoned pip and they he totally different amounts I was ment to owe over an over payment that is from back in 2007 to 2009 when I only got pip in 2022 they told me to call for which I did yet again and was robbed off yet again I have wrote to do but still in being told  its right when I have added up my ten year deductions and it's in double figures of thousands and just couldn't cope with  always being dismissed knowing it's not right but just made me severely depressed and just have up I truly believe I am owed a lot of money no from wrong deductions but I had enough thanks

From start my claim has been wrong I worked full time  and my mum died so I ended going on Sep through dwp ment to be a 13 week period which dwp didn't tell me they just told me that they would inform me when this time was up  I constantly had footnotes sent across to dwp automatically from my doctor well it was 39 weeks before dwp told me that I should have stopped claiming Ssp 16 weeks earlier which I didn't know I had to do  so  I I had had a breakdown  due to grief and my doctor was not sending 3 month footnotes into dwp I was told I was to claim esa but I would have to stay on ssp money until I had a medical which I cancelled my first 1 and was told I would get next 1 in post which I did but it came the day after date on letter so 3rd was ment to be sent which never arrived and my Ssp payment was stopped and was told I wasn't entitled to any money until I had medical which would take up to 6 months so I feel into deep depression  and  was in bad way suicidal I also took overdose 2 times due to it all the whole time I still had footnotes sent across to dwp I was told after 5 months only way I could claim any money I would have to claim  income support which I did but was declined as I was not got enough to work but dwp knew there were getting footnotes for me the whole time anyway in September 2018 I was awarded esa and given backlash just under £700 for the whole period of time at ssp rate which should have been backdated to me at esa rate which was just under £3000 I rang up to quietly it but was told I was wrong and been same answer to everything I have questioned and just was not mentally strong enough so just let them get away with it but enough enough they have ripped lots of people off and I truly believe in one of those people who has been ripped off please help me  I have suffered with coping in severe hardship due to undergarments for many years now that includes pip appeals being given low points which a high court has told dwp that they have awarded people points for pip wrongly and well under what should have been awarded again I believe that includes my case and failed pip claims and appeals
