Equifax! is worth to Complain

Hello members,

I have a huge problem with Equifax. I hope someone could give me an advice.

I have excellent credit score with Experian and CallCredit but I turned down for a loan and the lender advised me to contact Equifax.

I used to be a member so I just updated my card details and the nightmare started. The ware failing to update my details my recent addresses and I was not on the electoral roll however the Council supplied my details to them the same time as to other agencies.

After two months they managed to correct my credit score so I become good. Then after three days Shop direct increased my credit limit and my score went down to Poor.

I phone them up to find out the reason because it usually a positive effect and I had a completely annoying conversation with a completely useless lady from probably other side of the world.

What ever I was asking She keep repeated the same statement what I assume she was reading to me on the phone as a general transfer to this kind of questions like this. "What caused my score to droop 120 points within three days?"

She said she cannot provide me employee number she cannot provide me call identification number and She refused to tell me the complaining procedure.

Is there any way I can complain about Equifax. Is there a regulatory Body observing credit reference agencies? Do i have to be a paid member with all three main agencies to maintain an excellent score?
