called for interview at job centre

i have received a letter today saying i must attend an office interview, we re reviewing your benefits and circumstances . This is for the 11th Oct.
signed by compliance officer. I have been truthful and honest in all dealings with DWP and have never had anything like this before.

I'm afraid these are often triggered by an anonymous report, DWP have a duty to investigate no matter how unlikely the allegation.

We suggest that you have someone with you at the interview - to give moral support if nothing else!

try not to worry to much someone reported myself I was ill with worry done what most people did googled it and made matters worse, a compliance officer works in hand with fraud but are the lower level of the ladder if u are not going in under caution which they must tell u on the letter I would not worry about it as just doting the I,s and crossing the t,s in nearly all cases the compliance officers deal with, to close the file, the lady I saw was lovely and as stated was a nasty phone call whist I was in with my sister she checked to make sure I was getting the right support and as turned out was not and entitled to alittle bit more money so who ever did this did me a favour in the end good luck.

Thank you for taking the time to reply Shell, much appreciated . Yes i know i have nothing to fear because i have always been truthful and honest in my dealings with DWP. I know who has done this.

Hate people like this, they must have sad and bitter lives to want to cause harm to someone else.

I have also just been called for an interview on 10th October, 'to discuss some changes that may affect your benefits payments' Signed by 'Compliance Officer'. There have been no changes in my circumstances.
The letter asks for full details of any savings. I claim contribution-based ESA (Support group) and PIP. These benefits aren't affected by any savings. .
As I'm not claiming anything means-tested, Do I have to show them details of my savings? I find this extremely intrusive.
Also, are these interviews ever just triggered at random? That would be one less thing to worry about.
Thanks for any comments.
