Right, I definitely recommend sending a complaint letter and outlining the stress and worry its caused, along with the costs you have incurred along the way.
I sent mine to:
complaints department
tax credit office
preston
pr1 4at
and have been contacted by a member of their team to discuss this. He asked me exactly what I've spent sending stuff off to them. He's also going to investigate my missing documents.
Theres lots of helpful advice on the cab website here about what to say etc
it says
^"Delays
You should consider complaining if you have had to wait too long for:
a claim to be decided
an award to be changed
an explanation to be given.
The agency or local authority should have a target time for deciding a claim. You should find out what they are."^
so I think for you morgan this is particularly important to do, as I think it is disgraceful how long you've had to wait for answers.
I also saw on the tax credit casualties website, that it is helpful to keep a timeline of events, so for example:
1/05/15 received letter stating another adult living with you/childcare costs wrong
02/05/15 spoke to frank at 2;30pm. He said xxxxxxx
05/05/15 sent letter recorded delivery. tracking number is xxxxxxxxx
06/05/15 tracking number confirms delivery. signed for by jane at 8:15am
etc. Also take screen shots of your tracked item saying it had been delivered, and keep a copy of that with the receipt for that particular item sent.
