While purchasing a new SIM card contract I got rejected because my credit check failed. I read all the articles in these forums that said I had to wait or contact Experian directly, but my credit score is actually ok (you can check it with Experian) and I find it laughable a credit score rejects me for a £20 monthly payment when I don't have any debts and my finances are good.
Solution: Just go to an O2 shop, they will be able to sort it as it's likely one of these things has confused the system and that's why you got reported.
1) I recently moved home and my bank address wasn't up to date, so lady at O2 put my old address and that solved the issue. The system was rejecting me because my bank/residential address didn't match.
2) Also check for discrepancies on you bank and personal address, wrong postcodes or spelling mistakes in your name or date of birth.
3) If this is not your case it could also be you registered two accounts in the same email address, that's
something I saw in some of the forums that can flag you (e.g. someone buying a sim card for a relative, so system can failed because there are two identities in same account)
4) if you genuinely have a credit score issue you would know about it. So if this is not your case, just go to an O2 shop and talk to someone competent, they will sort it out for you. I went to Greenwich in London.
Hope that works.
