Still nothing

My first complaint was on 22nd of Sept. and on the 23rd of Sept I received a phone call from Virgin Money's complaints department assuring me that there was a problem and that it has been fixed now and the credit increase will be loaded on my card that night (23rd sept.) so two days later 25th still nothing I phoned the customer line they make me hold the line for about 5 min after what the guy on the phone said the consultant was not available he sent them an email to investigate it. On the 28th I sent feedback and received no response and now on the 29th there is still nothing and no response!
