Incorrect Errears Account

Guys, you want my money and I want to give you my money - I have tried to contact whoever my account has been handed over to - the account balance is incorrect and I have so been ready to settle the account. However I never receive any calls back from them and I am not going to waste my own airtime to try and sort out what feels like an empty white room. What am I supposed to do? I want to settle this as in yesterday already. It's been years yo :/
