POOR SERVICE !!!

so here it goes, something so simple turns out to be a nightmare . I am in the process of settling my vehicle finance as my car has been recently written off , my insurers are on the final stages and as a result they have asked me to gain the banking details from MFC in order to make payment . i had informed them that the settlement letter states that MFC banking details is on the beneficiary listing on internet banking ,however they require a letter from MFC confirming the banking details in full . So this does not sound difficult at all , until i called the call centre of MFC , what a waste of time , i held on for ages , the first consultant told me he cant help me , the second said she will sms me the bank details only to find out that it isnt the full details . All i want is a letter from mfc STATING THEIR BANKING DETAILS IN FULL , IS THAT TO HARD!!, i have been paying my finance for over a year and i think its time look at another company to finance my next vehicle .
