Hi everyone
Hoping for some advice!
I changed job mid year 2014 and dropped salary by £8k (£6k if including tc disregard) they wouldn't adjust my payments as have to wait until end of tax year which was fine but I would have expected an increase this tax year.
My childcare has dropped so knew that would reflect my claim but I estimated I would get roughly the same about £600 a month well they have apparently overpaid me £2k and are now taking £160 per month from my new award 
This is a lot of money for me as a single parent earning around £800 a month wages with childcare to pay, they have put a request in to reduce the overpayment but said it can take 6 weeks and isn't definite.
Does anyone have experience of this and do you think I should ring the overpayment helpline? Luckily I have a credit card that will help with daily expenses this month but I need to get something sorted.
Thanks for reading and sorry if it makes no sense quickly typing on my lunch!
