Don't know if it helps at all but in the past I had terrible trouble with the internet customer service team....their ability to comprehend & communicate being, how shall we say, somewhat questionable.
In the end I bypassed the internet team altogether and went to the 'normal' customer relations officers,
cro.support@egg.com who were much more helpful.
They apologised and refunded my PPI premiums...Could be worth a try!
I'm now requesting refund of a '0% Anniversary Offer' balance transfer fee of £356, the thieving muts made no mention of any fees at any point....all the internet team did was refer me to the small print.
