Still waiting for promised adjustment

After posting a complaint on Hello Peter (The only way to get actual assistance sadly) I was delighted this week to hear that my account was going to be credited for the incorrectly billed bundles and out of bundle rates. I have the confirmation sms. I was told on the phone that the I'd need to wait 2-3 days before my account updated. Today is day 3 and still my account is not reflecting the credit. I want assurance that the account will be credited and I do not trust the sms confirmation. I'd like to see that my account has had the credit deducted as promised. <br> Please can someone fix my account once and for all?!
