O2 Late payment markers

[Schmidlin]

Hello,

I've recently had a payment plan set up with O2 for a couple of bills due to being unemployed,

I then got a job and agreed a payment plan for these bills,

whereby I was told,

that because I had rung up and set something up with them to pay my outstanding bills,

that there would not be any late payment markers placed on my credit file.

 

However, they have now put late payment markers on my account.

 

I sent an email to their credit referrals email address

and was told that even though they had told me over the phone

and that I had an online chat with O2 stating that I should not get any problems

or markers put on my account, that legally they have to mark my account

as late as my payment for that month was late.

 

The question I have is,

I have paid other months late, but no markers have been put against my file,

but O2 now state that they are legally obliged to mark my account as it is used?

 

Can I use this fact to get my markers removed as they said originally?

 

I've just spent a 6 months clearing debt and making sure I'm not late on anything

and now this and my credit score with Experian has dropped from 658 to 400.

 

Any advice would be much appreciated.
