02 messed my credit score

[qudsia]

02 have messed up my credit score so badly for which i have been declined a mortgage. I was billed more than what my contracted stated, i spoke to O2 several times in store, on the phone and email, eventually the case went to OMBUDSMAN and it was rectifed, O2 agreed that i did not owe antyhing and in fact i had been overcharged and that they owed me. O2 returned my money but now have somehow put me down as missed payments which has made my credit score attorcious. It states that i owe them £80 but i do not owe them anything as this was cleared when ombudsman got involved. I am extremely dissatisfied with 02, is there anyone that can assit urgently? how can i get my credit score up ASAP?

02 refunded me so how could they then claim miss payments when i was agreed that they owed me 

i would really appreciate if anyone could assit me....

So two months in and absolutely nothing has been done. To say I am angry is an understatement!!!! I emailed the email I was given by this forum but they said they can’t do anything about it- i called 02 again and they keep cutting me off. An utter disgrace of a company. My mortgage has been declined and i’ve lost so much money Coz of 02s thick mistakes

I'd suggest using Resolver to make a complaint.

If not resolved by O2, you can then go to the ombudsman again.
