False default ruining credit history

[Knight123]

I am extremely upset.
I ended my my contract with Vodafone however they continued to charge me an amount I didn’t owe. This has now defaulted on my credit history under REPOSESSION! and makes it extremely difficult to get a mortgage or credit cards. Please is anyone able to help me resolve this before I have to go to the papers and internet to raise awareness of boycotting Vodafone.
